wifi: rtw89: regd: avoid using BITMAP_FROM_U64() to assign function bitmap
Since there are two function features for now, func_bitmap[] has single
one element, which BITMAP_FROM_U64() generating two elements is exceeded.
Change to assign function bitmap barely.
With i386-allmodconfig (a 32 bit system), it throws
