tty: serial: uartlite: allow 64 bit address
[ Upstream commit 3672fb65155530b5eea6225685c75329b6debec3 ]
The base address of uartlite registers could be 64 bit address which is from
device resource. When ulite_probe() calls ulite_assign(), this 64 bit
address is casted to 32-bit. The fix is to replace "u32" type with
"phys_addr_t" type for the base address in ulite_assign() argument list.
Fixes: 8fa7b6100693 ("[POWERPC] Uartlite: Separate the bus binding from the driver proper")
