Hello Simon,

Using this driver on socfpga gen5 with DM_I2C enabled leads to a data abort as the 'i2c' reset property cannot be found (the gen5 dtsi does not provide reset-names).
The actual bug was to check 'if (&priv->reset_ctl)', which is never false.
While at it, convert the driver to use 'reset_get_bulk' instead of looking at a specific named reset and also make it release the reset on driver remove before starting the OS.
