This commit splits the support code for LogicPD's mx31lite hardware
into module and board specific parts.

This introduces a new mandatory coreparam called 'mx31lite_baseboard'
which specifies the base board support to use. For now, only the LiteKit
development board is supported, and developers of own boards are
encouraged to use that as reference.

The UART support moved to the board code.
Some comments were amended along the way.

According to Russell King handle_edge_irq is only useful for "edge-based
inputs where the controller does not remember transitions with the input
masked."

So using handle_edge_irq unconditionally for both edge and level irqs is
wrong.  Testing showed that the controller does remember transitions
while the interrupt is masked.  So use handle_level_irq unconditionally.

We get rid of CTS/RTS lines on uart0 on our platform.
This is the port we use as main kernel console. We do not
want it to be blocking because of CTS/RTS signals, not allowing
the system to boot or print messages.

However we often use it with a bluetooth module needing CTS/RTS
lines as backup login in case of trouble. To be able to use it,
we assert CTS low so that the module can always send chars.

The chip is actually located on the module, not on the base board. But
other base boards might add more SPI devices, so the spi_board_info
struct must be separated from the module code.
