Recent DEBUG_LL and uncompress.h changes removed the check_port()
as pointed out by Cory Maccarrone <darkstar6262@gmail.com>.
This causes some boards to not boot, so add back the MDR1 register
check. The MDR1 register tells the mode of omap uart. Based on
an earlier patch by Cory Maccarrone <darkstar6262@gmail.com>.

This change adds in the necessary clocks and mux pins for UART
control on omap7xx devices. I also made a change in the serial
code to only try and initialize two UARTs in omap_serial_init, as
these devices don't have three.

Fix GPIO numbers and smc91x for 2430sdp. The earlier code
had cut and paste errors from 3430sdp code. Also, 2430
has five GPIO banks for a total of 160 GPIO lines.

The only difference between them is the physical address of the
uart4 port, which is only present in 36xx chips.
We don't really need to care about keeping these 2 functions, since
the decision to use uart4 is more cleanly done later when we do have
access to omap_revision variable.

Most OMAP3-based boards use exactly the same code for .map_io method in
the machine_desc structure.
This patch introduces omap3_map_io and updates board-* files to use it
as .map_io method.

OMAP3530 CBB package can have GPIO126 muxed on 2 pins: mmc1_dat4 and
cam_strobe. This causes a problem with current multipath GPIO mux
handling, which muxes both pins as GPIO126 and makes the GPIO unusable.
Fix this by not muxing any pins if multipath GPIO is detected and
just print a warning instead. It's up to board files to set correct
mux using omap_mux_init_signal and pin name.

Omap DMA controller can prefetch data in advance in case of
destination synchronized data transfer. This may increase
performance when target HW block doesn't have fifo.
Data is waiting for transfer request in DMA fifo instead of read from memory.

AM3505/3517 doesn't have IO wakeup capability, so we do not need to set
the bit OMAP3430_EN_IO and the bit OMAP3430_EN_IO_CHAIN in the register
PM_WKEN_WKUP when the system enters suspend state.
Tested on AM3517EVM and OMAP3530EVM.
