Subject: [PATCH] serial: ns16550: Correct the base address type
Currently ns16550_serial_assign_base() treats the argument 'base'
with type `ulong`. This is incorrect because the base address was
obtained from device tree with type `fdt_addr_t` that can represent
a physical address larger than 32-bit in a 32-bit system.
Fixes: 9e6ce62190b7 ("serial: ns16550: Fix ordering of getting base address")
