serial: 8250_em: Fix UART port type 



commit 32e293be736b853f168cd065d9cbc1b0c69f545d upstream.

As per HW manual for  EMEV2 "R19UH0040EJ0400 Rev.4.00", the UART
IP found on EMMA mobile SoC is Register-compatible with the
general-purpose 16750 UART chip. Fix UART port type as 16750 and
enable 64-bytes fifo support.
