The FSP release version 001 for Intel Queensbay has a bug which
could cause random endless loop during the FspInit call. This bug
was published by Intel although Intel did not describe any details.
Describe this information in the x86 doc so that U-Boot Queensbay
support is invulnerable.

Using __DATE__ and __TIME__ results in an error due to -Werror=date-time
with gcc-4.9 (__DATE__ / __TIME__ might prevent reproducible builds) so
switch these over to U_BOOT_DATE / U_BOOT_TIME

This patch cleans up the quark MRC codes coding style by:
- Remove BIT0/1../31 defines from mrc_util.h
- Create names for the documented BITs and use them
- For undocumented single BITs, use (1 << n) directly
- For undocumented ORed BITs, use the hex number directly
- Remove redundancy parenthesis all over the codes
- Replace to use lower case hex numbers

Apparently the firmware's board rev response includes both the board
revision and some other data even on the RPi1. In particular, the
"warranty bit" is bit 24. We need to mask that out when looking up the
board ID.

The callee (arch/arm/lib/cache-cp15.c) has a #ifdef
CONFIG_SYS_DCACHE_OFF conditional. The same conditional in the
caller (arch/arm/mach-uniphier/cache_uniphier.c) is redundant.

The L2 cache is used as a temporary SRAM on SPL.
Now the secondary CPUs store the necessary code for jumping to
Linux on their L1 I-caches. So, the L2 cache can be disabled
much earlier, at the very entry of U-Boot proper (lowlevel_init).
This makes the boot sequence clearer.
Also, as the L1 cache has been disabled by the start.S,
enable_caches() does not need to do it again.

Currently, the secondary CPU(s) are kicked three times:
Boot ROM ---(kick)--> SPL ---(kick)--> U-boot ---(kick)--> Linux.
It makes the boot sequence very complicated.
This commit merges the first and the second kicks, so the secondary
CPU(s) can directly jump from SPL to Linux.
arch/arm/mach-uniphier/smp.S is no longer necessary.
Linux boot test passed.

The current implementation for baudrate calculation is incorrect.
This part from the formula:
"2 ^ (n + 1)" is not equivalent to (1 << n) but to (2 << n)!
This patch fixes this and moves this calculation to a function instead of using a macro.
This new function is taken from the Linux kernel.
This was detected and tested on the Marvell Armada A38x DB-88F6820-GP eval board.
