x86: Add request_standard_resources to x86_init
The 32bit and the 64bit code are slighty different in the reservation
of standard resources. Also the upcoming Moorestown support needs its
own version of that.
Add it to x86_init_ops and initialize it with the 64bit default. 32bit
overrides it in early boot. Now moorestown can add it's own override
w/o sprinkling the code with more #ifdefs
