ACPICA: Fix largest possible resource descriptor index
ACPI_RESOURCE_NAME_LARGE_MAX should be equal to the last actually
used resource descriptor index (ACPI_RESOURCE_NAME_CLOCK_INPUT).
Otherwise 'resource_index' in 'acpi_ut_validate_resource()' may be
clamped incorrectly and resulting value may issue an out-of-bounds
access for 'acpi_gbl_resource_types' array. Compile tested only.
Fixes: 520d4a0ee5b6 ("ACPICA: add support for ClockInput resource (v6.5)")
