mfd/axp20x: avoid irq numbering collision
IRQ numbers in axp20x devices are defined with high-order bit first
in each IRQ enable/status registers. On Intel platforms it is more
common to number IRQs with least significant bit first. Therefore,
sharing IRQ# between the two is very difficult. Since AXP288 is a
customized PMIC for Intel platform and the amount of shared IRQs are
very small, we use separate IRQ numbering. This also fixes collision
and a duplicate in WBTO interrupt.
e.g. For the 16 interrupts controlled in IRQ enabled registers 1 & 2,
on axp20x for ARM, the PMIC local IRQ numbers and register bits are
mapped as:
IRQ#: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
---------------------------------------------------------
ARM: 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0
Intel: 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7
