Move FCH header to a location accessible by all archs
A new header fch.h was created to store registers used by different AMD
drivers.  This header was included by i2c-piix4 in
commit 624b0d5696 ("i2c: piix4, x86/platform: Move the SB800 PIIX4 FCH
definitions to <asm/amd/fch.h>"). To prevent compile failures on non-x86
archs i2c-piix4 was set to only compile on x86 by commit 7e173eb82a
("i2c: piix4: Make CONFIG_I2C_PIIX4 dependent on CONFIG_X86").
This was not a good decision because loongarch and mips both actually
support i2c-piix4 and set it enabled in the defconfig.

Move the header to a location accessible by all architectures.
