serial: pic32: convert to_pic32_sport() to an inline

Browse Source 
'c' is not in wrapped in parentheses in the to_pic32_sport() macro, so
it might be problematic wrt macro expansion. Using an inline is always
safer in these cases. Both type-wise and macro-expansion-wise. So switch
the macro to an inline.
