PCI: rockchip: Use 64-bit mask on MSI 64-bit PCI address

commit cdb50033 upstream.

A 32-bit mask was used on the 64-bit PCI address used for mapping MSIs.
This would result in the upper 32 bits being unintentionally zeroed and
MSIs getting mapped to incorrect PCI addresses if the address had any
of the upper bits set.

Replace 32-bit mask by appropriate 64-bit mask.

[kwilczynski: use GENMASK_ULL() over GENMASK() for 32-bit compatibility]
Fixes: dc73ed0f
