ACPICA: Minimize the differences between linux GPE code and ACPICA code base

We have ported Rafael's major GPE changes
(ACPI: Use GPE reference counting to support shared GPEs) into ACPICA code base.
But the port and Rafael's original patch have some differences, so we made
below patch to make linux GPE code consistent with ACPICA code base.

Most changes are about comments and coding styles.
Other noticeable changes are based on:

Rafael: Reduce code duplication related to GPE lookup
https://patchwork.kernel.org/patch/86237/

Rafael: Always use the same lock for GPE locking
https://patchwork.kernel.org/patch/90471/

A new field gpe_count in struct acpi_gpe_block_info to record the number
of individual GPEs in block.

Rename acpi_ev_save_method_info to acpi_ev_match_gpe_method.
