A new header fch.h was created to store registers used by different AMD drivers. This header was included by i2c-piix4 in commit624b0d5696
("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 commit7e173eb82a
("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. Fixes:624b0d5696
