Subject: [PATCH 2/2] serial: 8250pci: Recast inb return value

inb returns u8 that's why is necessary to do recast.

Compilation warning:
  CC      drivers/serial/8250_pci.o
drivers/serial/8250_pci.c: In function 'pci_ite887x_init':
drivers/serial/8250_pci.c:825: warning: cast to pointer from integer of different size
