Subject: [PATCH v3 0/4] ACPI / EC: Add quirk modes for boot EC support

It's reported that Asus laptop X580VD/X550VXK/GL720VMK/FX502VD/FX502VE have
a BIOS bug where the ECDT correctly states that EC events trigger GPE 0x23,
but the DSDT _GPE method incorrectly returns GPE 0x33.

This patchset fixes this issue.

v2: Stops doing craps related to EC_ID (it's already too complicated), and
    reduces one unnecessary boot parameter. For the final bug fix, prefers
    the fix from endlessm.com developers.
v3: Removes improper statments related to _STA as acpi_get_devices() has
    executed _STA before invoking ec_parse_device() adds detailed
    explanation for why acpi_ec_dsdt_probe() is a wrong approach.
    Carlo Caione helps to add a new quirk for GL720VMK.
