[ARM] 5541/1: serial/amba-pl011.c: add support for the modified port found in Nomadik

Browse Source 
The Nomadik 8815 SoC has a slightly modified version of the PL011 block.
The patch uses the different ID value as a key to select a vendor
structure that is used to keep track of the differences, as suggested
by Russell King.
