treewide: convert bd_t to struct bd_info by coccinelle

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

Booting an lz4-compressed kernel image fails on our powerpc board with
-EPROTONOSUPPORT. Adding a bit of debug prints, we get

  magic: 0x184d2204
  flags: 0x64
  reserved0: 1
  has_content_checksum: 1

  max_block_size: 0
  reserved2: 0

So the magic is ok, but the version check fails, also some reserved
bits are apparently set. But that's because the code interprets the
"flags" and "block_descriptor" bytes wrongly:

Using bit-fields to access individual bits of an "on the wire" format
is not portable, not even when restricted to the C flavour implemented
by gcc. Quoting the gcc manual:

   * 'The order of allocation of bit-fields within a unit (C90 6.5.2.1,
     C99 and C11 6.7.2.1).'

     Determined by ABI.

and indeed, the PPC Processor ABI supplement says

   * Bit-fields are allocated from right to left (least to most
     significant) on Little-Endian implementations and from left to
     right (most to least significant) on Big-Endian implementations.

The upstream code (github.com/lz4/lz4) uses explicit shifts and masks
for encoding/decoding:

    /* FLG Byte */
    *dstPtr++ = (BYTE)(((1 & _2BITS) << 6)    /* Version('01') */
        + ((cctxPtr->prefs.frameInfo.blockMode & _1BIT ) << 5)
        + ((cctxPtr->prefs.frameInfo.blockChecksumFlag & _1BIT ) << 4)
        + ((unsigned)(cctxPtr->prefs.frameInfo.contentSize > 0) << 3)
        + ((cctxPtr->prefs.frameInfo.contentChecksumFlag & _1BIT ) << 2)
        +  (cctxPtr->prefs.frameInfo.dictID > 0) );

    /* Flags */
    {   U32 const FLG = srcPtr[4];
        U32 const version = (FLG>>6) & _2BITS;
        blockChecksumFlag = (FLG>>4) & _1BIT;
        blockMode = (FLG>>5) & _1BIT;
        contentSizeFlag = (FLG>>3) & _1BIT;
        contentChecksumFlag = (FLG>>2) & _1BIT;
        dictIDFlag = FLG & _1BIT;
        /* validate */
        if (((FLG>>1)&_1BIT) != 0) return err0r(LZ4F_ERROR_reservedFlag_set); /* Reserved bit */
        if (version != 1) return err0r(LZ4F_ERROR_headerVersion_wrong);        /* Version Number, only supported value */
    }

Do the same here, and while at it, be more careful to use unaligned
accessors to what is most likely unaligned. Also update the comment to
make it clear that it only refers to the lz4.c file, not the following
code of lz4_wrapper.c.

This has been tested partly, of course, by seeing that my
lz4-compressed kernel now boots, partly by running the (de)compression

The FSP-S changes the ITSS priorities. The code that tries to save it
before running FSP-S and restore it afterwards does not work as U-Boot
relocates in between the save and restore. This means that the driver
data saved before relocation is lost and the new driver just sees zeroes.

Fix this by allocating space in the relocated memory for the ITSS data.
Save it there and access it from the driver after relocation.

This fixes interrupt handling on coral.

Also drop the log_msg_ret() in irq_first_device_type() since this function
can be called speculatively in places where we are not sure if there is
