ARM: shmobile: Rework the PMIC IRQ line quirk

Browse source

Rather than hard-coding the quirk topology, which stopped scaling,
parse the information from DT. The code looks for all compatible
PMICs -- da9063 and da9210 -- and checks if their IRQ line is tied
to the same pin. If so, the code sends a matching sequence to the
PMIC to deassert the IRQ.
