The macro mx31_revision() used to take the global variable system_rev to
determine the CPU revision number. However, this number is expected to
be set by the bootloader and is usually zero (at least on my MX31 based
boards here). More than that, it is usually taken to identify the
board's revision, not the CPU's.

Fix that by reading the the CPU's SREV register instead.

Right now, mx31_read_cpu_rev() is called from mx31_clocks_init() which
is admittedly not a good place for it. However, we need to enable the
IIM clock first, and the clock code also has conditional code that
depends on mx31_revision() returning the right thing.

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.
