Even though eSDHC-A001 is not documented on the i.MX51 errata document,
I have confirmed with the NXP design team that this erratum does affect
i.MX51, so fix the problem by selecting SYS_FSL_ERRATUM_ESDHC_A001

The motivation for moving MX25 selection to Kconfig is to be

can be selected at SoC level instead of board level.
This selection method also aligns with the way other i.MX SoCs are

The fixed regulator for overriding BIOS_DISABLE had been modelling
backwards (i.e. the GPIO polarity and the enable-active-low/high
property had both been inverted), causing the 'regulator' command
to always print/expect 'disabled'/'enabled' backwards.
This fixes the mix-up and models it correctly:
* the GPIO is low-active
* the regulator should be enabled (enable-active-high) during
boot-on initialisation

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]: CPU 0: Machine Check: 0 Bank 4: c400000000010151

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.
