mfd: max77705: Mark PASS2 revision as supported

Browse Source 
The existing driver takes a safe approach and only probes on tested
MAX77705 revisions. The only tested revision at the time was
PASS3. PASS2 chips are present in the Samsung Galaxy S10/S10+/S10e
devices.

Testing on the S10 and S10+ shows the driver operates correctly on
PASS2: interrupts are registered and fire, bind and unbind release the
I2C device cleanly, and the charger and fuel gauge report plausible
values, charging the battery to the same voltage as the vendor kernel,
haptic feedback works.
