libpayload: x86: Add read/write{8,16,32} variants that match coreboot

Add the now coreboot standard MMIO read/write accessors that were
    already defined for other architectures but not x86.

This leaves the old read/write{b,w,l} variants in place as was done
    on the other architectures, presumably to support old payloads that
    have not been updated.
