Add bcd2bin() as linuxkpi_bcd2bin(). Libkern does provide a bcd2bin()

Fortunately this is only seen in one driver so far and it seems easier

Remove page zeroing code from consumers and stop specifying
VM_ALLOC_NOOBJ. In a few places, also convert an allocation loop to
simply use VM_ALLOC_WAITOK.
Similarly, convert vm_page_alloc_domain() callers.
Note that callers are now responsible for assigning the pindex.

Linux KPIs like pci_resource_start/len assume that BARs have been
allocated, but FreeBSD lazily allocates BARs if it cannot allocate the
firmware-allocated BARs. Thus using the Linux KPIs must force allocation
of the BARs rather than returning 0 for the start and length, which can
crash drm-kmod drivers that assume the BARs are valid. This is needed
for the AMDGPU driver to be able to attach on SiFive's HiFive Unmatched.
