Marek Vasut be23774ed1 ARM: imx: imx27: Introduce and use UART_BASE_ADDR(n) 
Introduce helper macro UART_BASE_ADDR(n), which returns Nth UART base
address. Convert all board configurations to this new macro. This is the
first step toward switching CONFIG_MXC_UART_BASE to Kconfig. This is a
clean up, no functional change.

The new macro contains compile-time test to verify N is in suitable
range. The test works such that it multiplies constant N by constant
double-negation of size of a non-empty structure, i.e. it multiplies
constant N by constant 1 in each successful compilation case.

The non-empty structure may contain C11 _Static_assert(), make use of
this and place the kernel variant of static assert in there, so that
it performs the compile-time check for N in the correct range. Note
that it is not possible to directly use static_assert in compound
statements, hence this convoluted construct.
