MIPS: alchemy: provide visible function prototypes to board files

Board files under arch/mips/alchemy/ define functions called from
db1xxx.c but their prototypes are only in that .c file instead of being
declared in a common header. This causes several build warnings about
missing prototypes. Provide these prototypes in a new header and include
it where necessary.
