ACPI / EC: Add HP Folio 13 to ec_dmi_table in order to skip DSDT scan

HP Folio 13's BIOS defines CMOS RTC Operation Region and the EC's
_REG method will access that region.  To allow the CMOS RTC region
handler to be installed before the EC _REG method is first invoked,
add ec_skip_dsdt_scan() as HP Folio 13's callback to ec_dmi_table.
