[PATCH v2 2/2] ARM: dts: ux500: Use AB8505 charger compatible

[Linus Walleij <linusw@kernel.org>]

Identify the AB8505 charger using its variant-specific compatible and
retain the AB8500 compatible as a fallback for the existing driver. This
selects the AB8505 interrupt constraints from the binding.

The AB8505 interrupt table explicitly omits the five interrupt sources
belonging to the AB8500 main charger. Remove these nonexistent interrupts
from the AB8505 charger node, leaving its nine USB charger interrupts.

Fixes: bc324d447fba ("ARM: dts: ux500: Add interrupts to charger")
