[MIPS] Alchemy: Fix use of __init code bug exposed by modpost warning

WARNING: vmlinux.o(.text+0x1ca608): Section mismatch: reference to
.init.text: add_wired_entry (between 'config_access' and 'config_read')

by refactoring the code calling add_wired_entry() from config_access() to
a separate function which is called from aau1x_pci_setup(). While at it:

- make some unnecassarily global variables 'static';

- fix the letter case, whitespace, etc. in the comments...
