kernel: Drop non-standard GNU inline assignment syntax

* We needed this previously due to our gcc2 compiled kernel.
* Now that our kernel is always latest gcc, we can move to the
c++20 syntax for inline assignment.
* Improves compatibility with clang, less GNU-specific stuff

drivers: Fix 64 bit BAR checks and remove redundant masking.

Fix address type mask to use the right bits via PCI_address_type. The
previous 0xc value applies to the upper of the two address type and
the prefetchable bit instead of the two adddress type bits. This would
cause prefetchable 64 bit BARs to be misidentified as not being 64 bit.

Remove address masking as this is already done on the field in pci_info.

Use uint64 instead of phys_addr_t explicitly as on pure 32 bit platforms
this would otherwise result in a shift greater than type size.

Note that the sizes should theoretically be adjusted as well, but in all
of these cases a size needing the upper 32 bits doesn't make much sense.
