"0x01 0x00 0x01" becomes 0x0 0x0 0x0 0x0 0x0 0x1 0x0 0x1"

arm64: issue ISB after updating system registers

ARM Architecture reference manual clearly states that PE pipeline
should be flushed after changes to some system registers. Refer to
paragraph "B2.3.5 Memory Barriers" at page B2-92 of "Arm Architecture
Reference Manual ARMv8 for ARMv8-A Architecture Profile" (ARM DDI
0487B.a).

Failing to issue instruction synchronization barrier can lead to
spurious errors, like synchronous exception when accessing FPU
registers. This is very prominent on CPUs with long instruction
pipeline, like ARM Cortex A72.

This change fixes the following U-Boot panic:

Revert "riscv: sifive: fu540: Add gpio-restart support"

As part of merging the next branch in to master, the sifive_fu540 will
fail to link:
riscv64-linux-ld.bfd: lib/built-in.o: in function `panic_finish':
lib/panic.c:28: undefined reference to `do_reset'
make[2]: *** [spl/u-boot-spl] Error 1
make[1]: *** [spl/u-boot-spl] Error 2
make: *** [sub-make] Error 2

And while the "fix the build" option of enabling CONFIG_SPL_SYSRESET may
solve the issue, it is unclear that it is the correct path exactly.  For
the moment, I am reverting this commit and take a "revert the revert"
and proper fix as soon as it's available.

This reverts commit cdae446461191714d692190da1ad4344398adc57.

video: restore CONFIG_VIDCONSOLE_AS_LCD as boolean

This patch restores CONFIG_VIDCONSOLE_AS_LCD as boolean
and introduce a separate sting as CONFIG_VIDCONSOLE_AS_NAME
to search this string in stdout used as videoconsole.

This patch avoid issue with board defconfig or code expecting
CONFIG_VIDCONSOLE_AS_LCD as boolean.
