platform/x86: Make dual_accel_detect() KIOX010A + KIOX020A detect more robust

Browse Source 
commit 085fc31f81 upstream.

360 degree hinges devices with dual KIOX010A + KIOX020A accelerometers
always have both a KIOX010A and a KIOX020A ACPI device (one for each
accel).

Theoretical some vendor may re-use some DSDT for a non-convertible
stripping out just the KIOX020A ACPI device from the DSDT. Check that
both ACPI devices are present to make the check more robust.
