haswell: Fix VGA option rom INT15 handler 

The format of this function changed but was not updated in
all mainboards.  This fixes BaskingRidge and WTM2.

The int15 handler no longer takes a regs structure as an
argument and instead uses global variables.  The yabel interface
is now similar enough that we can drop the duplicate handler.
