ASoC: Intel: bytcr_wm5102: Add support for Lenovo Yoga Tab 3 Pro YT3-X90
The Lenovo Yoga Tab 3 Pro YT3-X90 x86 tablet, which ships with Android
with a custom kernel as factory OS, does not list the used WM5102 codec
inside its DSDT.
So acpi_dev_get_first_match_dev() is going to fail on this board.
Fallback to using "spi-$(mach->id)" as codec device name in this case
to allow bytcr_wm5102 to work on these tablets.
