amd/agesa/*/gcc-intrin.h: Invaild inline asm

The 'm' (a memory reference) constraint makes little sense here since we
    are talking about a fs relative read, rather 'ir' (immediate or
    register) constraint is more sensible.

N.B. The 'p' constraint allows anything which fits the form of an address
    calculation where the 'ir' constraint is just a register /xor/
    immediate. Hence would produce better code here however, unfortunately,
    clang does not currently support it properly.

The %b and %w constraints are also redundant and only hide errors.

The functions writefsword() and writefsdword() should use ir instead of
    iq. iq is unnecessarily restrictive (it is only required for writing
    bytes).

The cld in stosb is redundant (and the constraints are unnecessarily
    complicated). Note that The ABI guarantees that the direction flag is
    cleared. i.e. eax, ecx, edx are caller-saved, returned value in eax,
    eax+edx, st0, yaddayadda, direction flag cleared. In fact bad things can
    happen if you set it in some asm and do not clear it until the end of
    the asm.

Line wrap these extraneously long lines found with these particular functions.

Many thanks to Christoph Mallon  from #llvm for
    helping me with this.
