PCI: brcmstb: Fix build on 32bit ARM platforms with older compilers
Some older compilers have no implementation for the helper for 64-bit
unsigned division/modulo, so linking pcie-brcmstb driver causes the
"undefined reference to `__aeabi_uldivmod'" error.
*rc_bar2_size is always a power of two, because it is calculated as:
"1ULL << fls64(entry->res->end - entry->res->start)", so the modulo
operation in the subsequent check can be replaced by a simple logical
AND with a proper mask.
