xen/arm: change parameter name 'pa' in ioremap_addr() definition.

In the current version of ioremap_addr() function, the declaration
uses the parameter name 'start' (consistenly with the other ioremap_*
function declarations), while the definition uses the parameter name
'pa'.
Change the parameter name 'pa' of function definition to 'start', thus
fixing a violation of MISRA C:2012 Rule 8.3 and keeping the consistency
with other ioremap_* functions.
