[ Upstream commit a4119108d2530747e61c7cbf52e2affd089cb1f6 ]
With this quirk, a PID device isn't required to have a strict logical_minimum of 1 for the the PID_DEVICE_CONTROL usage page.
Some devices come with weird values in their device descriptors and this quirk enables their initialization even if the logical minimum of the DEVICE_CONTROL page is not 1.
Fixes initialization of VRS Direct Force Pro
Changes in v6: - Change quirk name to better reflect it's intention
