thinkpad-acpi fails to load with newer Thinkpad X201s BIOS

The new BIOS has a slightly different EC version string.

Subject: [PATCH] thinkpad-acpi: Some BIOS versions don't end in WW, remove check

My X201s BIOS version string is 6QET46V1 (1.16 ). The
EC version string is 6QHT28WW-1.09. The driver was requiring that both
of these have 'WW' in positions 6 and 7. I don't know what the
significance of having 'V1' there instead is, but removing the test
makes the driver load on my machine.
