8331188615 x86: Rename existing FSP code to fsp1
Since there is now a new version of the FSP and it is incompatible with
the existing version, move the code into an fsp1 directory. This will
allow us to put FSP v2 code into an fsp2 directory.

Add a Kconfig which defines which version is in use.

Some of the code in this new fsp1/ directory is generic across both FSPv1
and FSPv2. Future patches will address this.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

4c9f4c5ee4 x86: braswell: cherryhill: Update dts for SPI lock down
Intel Braswell FSP requires SPI controller settings to be locked down,
let's do this in the chrryhill.dts and remove previous Kconfig option.

4a5a7fcac2 x86: braswell: Fix unexpected crash during Linux kernel boot
It was observed that when booting Linux kernel on Intel Cherry Hill
board, unexpected crash happens quite randomly. Sometimes kernel
just oops, while sometimes kernel throws MCE errors and hangs:

  mce: [Hardware Error]: Machine check events logged
  mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 4: c400000000010151
  mce: [Hardware Error]: TSC 0 ADDR 130f3f2c0
  mce: [Hardware Error]: PROCESSOR 0:406c3 TIME 1508160686 SOCKET 0 APIC 0 microcode 363

This looks like a hardware error per mcelog. After debugging, it
seems turning off turbo mode on the processor does not expose this
behavior, although U-Boot runs OK with turbo mode on. Suspect it is
related to an errata of Braswell processor.

To fix this, remove the Braswell cpu driver which does the turbo
mode configuration, and switch to use the generic cpu-x86 driver.
Also there is a configuration option in the FSP that turns on the
turbo mode and that has been turned off too.

Similar to its predecessor BayTrail, there are some work to do to
