ACPI: EC: add another DMI check for ASUS hardware

Commit 0adf3c746a73684b3f8c2821a584e1db998f61e9 introduced a regression
by making the ECDT validation test for ASUS hardware more restrictive.
The previous test used the dmi_name_in_vendors function which searches
a number of DMI fields, while the new test checked only the BIOS
vendor, which is known to not match on an ASUS F5GL laptop which
requires ECDT validation.

Add a rule to ec_dmi_table based on an alternative DMI pattern for
ASUS hardware as found elsewhere in the kernel.
