PCI: rockchip: Use u32 variable to access 32-bit registers

Browse source

commit 8962b2cb39 upstream.

Previously u16 variables were used to access 32-bit registers, this
resulted in not all of the data being read from the registers. Also
the left shift of more than 16-bits would result in moving data out
of the variable. Use u32 variables to access 32-bit registers
