The serial driver for iMX SOCs is continuosly changed if a
new SOC or not yet used port is used. CONFIG_SYS_<SOC>_<UART Port>
defines were used only to find the base address for the selected UART.
Instead of that, move the base address to the board configuration
file and drop all #ifdef from driver.

No board information is passed for MX53ARD, so remove get_board_rev function.

Now that none of the core checks CONFIG_NET_MULTI, there's not much point
in boards defining it.  So scrub all references to it.

CONFIG_L2_OFF is obsolete after the following commit:

e47f2db5371047eb9bcd115fee084e6a8a92a239
armv7: rename cache related CONFIG flags
Replace the cache related CONFIG flags with more meaningful
names. Following are the changes:
CONFIG_L2_OFF	     -> CONFIG_SYS_L2CACHE_OFF

Since imx5 does not provide L2 cache operations(Enable/Disable)
Simply remove CONFIG_L2_OFF and CONFIG_SYS_L2CACHE_OFF
