8250_men_mcb: remove unnecessary cast when reading register 

Fixes following sparse warning:

drivers/tty/serial/8250/8250_men_mcb.c:92:21: sparse: cast removes
    address space '__iomem' of expression
drivers/tty/serial/8250/8250_men_mcb.c:92:21: sparse: incorrect type
    in argument 1 (different address spaces) expected void const volatile
    [noderef] __iomem *addr got void *

Fixes: 2554e6ba28 ("8250_men_mcb: Read num ports from register data.")
