ACPI: sysfs: Change ACPI_MASKABLE_GPE_MAX to 0x100

ACPI: sysfs: Change ACPI_MASKABLE_GPE_MAX to 0x100

commit a7583e72a5f22470d3e6fd3b6ba912892242339f upstream.

The commit 0f27cff8597d ("ACPI: sysfs: Make ACPI GPE mask kernel
parameter cover all GPEs") says:
  "Use a bitmap of size 0xFF instead of a u64 for the GPE mask so 256
   GPEs can be masked"

But the masking of GPE 0xFF it not supported and the check condition
"gpe > ACPI_MASKABLE_GPE_MAX" is not valid because the type of gpe is
u8.

So modify the macro ACPI_MASKABLE_GPE_MAX to 0x100, and drop the "gpe >
ACPI_MASKABLE_GPE_MAX" check. In addition, update the docs "Format" for
acpi_mask_gpe parameter.
