drm/i915: Fix multiple off-by-one errors in intel_i2c
* the i2c pin numbers are 1 based as per intel spec but
we used the unit number as pin number, which is 0 based
* the gmbus array is 0 based, but the port number is 1 based
accesses into the port array are therefore off-by-one and this
only worked by chance before.
