irqchip/qcom-pdc: Move all static variables to struct pdc_desc

Browse source

There are multiple static variables used in the driver. Move all to struct
pdc_desc to better align with versioning support. Document them.

Add a new pdc->enable_intr() callback to point to the respective versions
specific enable function. Remove pdc_enable_intr() and __pdc_enable_intr()
and invoke pdc->enable_intr() from the call sites.

Locking in pdc_enable_intr() applies lock to all version specific
pdc->enable_intr() however lock is needed only for pdc_enable_intr_bank()
which uses a shared bank across on PDC v2.7 and PDC v3.0.

pdc_enable_intr_cfg() do not require locking as IRQ_CFG registers are one
per interrupt. Move the locking to pdc_enable_intr_bank().

No functional impact intended
