[PATCH] mfd: max77620: publish I2C and OF module aliases

[hpp.iscas]

MFD_MAX77620 became tristate without publishing any module alias for the
I2C driver. Device Tree I2C clients emit OF modaliases, while legacy
board-info clients use the existing I2C IDs, so both supported
enumeration paths need module metadata.

Publish the I2C table and add an OF table for the three documented
compatibles. Keep i2c_client_get_device_id() as the source of chip data
and leave MFD child registration unchanged.

Fixes: 0d084ee9ba87 ("mfd: max77620: Allow building as a module")
