touch_updater: Add preferred search path option to find_i2c_hid_device
find_i2c_hid_device traverses `I2C_DEVICES_PATH` to find a hid device.
However, in most cases this is being called from a function that already
has the top-level directory that contains the hid device. This change
allows the caller to provide a preferred search path thus optimizing
the search.
