serial: 8250: sparse warning of incorrect type
serial: 8250: sparse warning of incorrect type

fixed a sparse warning in 8250_core.c :
	incorrect type in assignment (different address spaces)

the warning was because an unsigned char pointer was being assigned to
a pointer of unsigned char __iomem type .
