mfd: Convert WM835x IRQ handling to use a data table

Browse Source

Rather than open coding individual IRQs in each function which
manipulates them store data for IRQs in a table which is then
referenced in the users.

This is a substantial code shrink and should be a performance win in
cases where only a single IRQ goes off at once since instead of
reading four of the second level IRQ registers for each interrupt
we read only the sub-registers which have had an interrupt flagged.
