MIPS: rb532: Fix MMIO UART resource registration
[ Upstream commit e93bb4b76cfefb302534246e892c7667491cb8cc ]
Since commit 6e690d54cfa8 ("serial: 8250: fix return error code in
serial8250_request_std_resource()"), registering an 8250 MMIO port
without mapbase no longer works, as the resource range is derived from
mapbase/mapsize.
Populate mapbase and mapsize accordingly. Also drop ugly membase KSEG1
pointer and set UPF_IOREMAP instead, letting the 8250 core perform the
ioremap.
Fixes: 6e690d54cfa8 ("serial: 8250: fix return error code in serial8250_request_std_resource()")
