gpiolib: acpi: Add robust bounds-checking for GPIO pin resources
Ensure that GPIO pin resource arrays are safely bounded before accessing
indices. Add explicit bounds checking in acpi_request_own_gpiod(),
acpi_gpio_irq_is_wake(), and acpi_gpiochip_alloc_event() to prevent
out-of-bounds array reads if the ACPI namespace provides malformed or empty
pin tables.
This change addresses potential safety issues arising from
inconsistent or invalid ACPI pin tables. It does not alter functional
behavior in well-formed tables.
