armv8: layerscape: don't initialize GIC in SPL

The BL31 expects the GIC to be uninitialized. Thus, if we are loading
the BL31 by the SPL we must not initialize it. If u-boot is loaded by
the SPL directly, it will initialize the GIC again (in the same
lowlevel_init()).

This was tested on a custom board with SPL loading the BL31 and jumping
to u-boot as BL33 as well as loading u-boot directly by the SPL. In case
the ATF BL1/BL2 is used, this patch won't change anything, because no

loop had back references, then subsequent loops without back references
use the wrong value of nlen. The value is larger, meaning that the string
terminator from nbuf is copied along to the main buffer, thus terminating
the string prematurely.

Adds basic support for ProxyDHCP

- ProxyDHCP allows a second DHCP server to exist alongside your main
  DHCP server and supply additional BOOTP related options
- When u-boot sends out a DHCP request, the real DHCP server will

  while simultaneously the ProxyDHCP server will respond with a blank
  client IP address and a `bootfile` option
- This patch adds CONFIG_SERVERIP_FROM_PROXYDHCP (default false) to
  enable this behavior and CONFIG_SERVERIP_FROM_PROXYDHCP_DELAY_MS
  (default 100) which tells u-boot to wait additional time after
  receiving the main DHCP response to give the ProxyDHCP response time
  to arrive
- The PXE spec for ProxyDHCP is more complicated than the solution

board: st: stm32mp1: update load address for FIT examples

Update kernel load address for FIT examples to avoid relocation:
- Kernel example uses Image.gz with U-Boot gzip decompression
  at final kernel location 0x0xC0008000.
- Copro example loads zImage at a correct location (0xC4000000),
  to avoid zImage relocation before decompression by kernel code.

An other solution to avoid zImage relocation is to align
the kernel load and entry address with the real location in FIT
(the relocation of zImage is skipped in U-Boot bootm command for
identical address) but it is less flexible because this offset
depends on FIT content:

For example:

## Loading kernel from FIT Image at c2000000 ...
   Using 'ev1' configuration
   Trying 'kernel' kernel subimage
     Description:  Linux kernel
     Created:      2020-10-22   9:08:32 UTC
     Type:         Kernel Image
     Compression:  uncompressed
     Data Start:   0xc20000cc

The kernel offset in FIT is 0xCC in FIT and zImage is decompressed at
0xC0008000 by kernel code:

kernel {
description = "Linux kernel";
data = /incbin/("zImage");
