AGESA: Fix CR0_PE bit define
AGESA code has wrong definition of CR0_PE bit (1 instead of 0).
PE [Protected Mode Enable] is 0 bit in CR0 register
(If PE=1, system is in protected mode, else system is in real mode)
Bit 1 is MP [Monitor co-processor]
(Controls interaction of WAIT/FWAIT instructions with TS flag in CR0)
System uses CR0_PE define, but I didn't expect any consequences because of this bug.
