Convert the rzg2l-gpt driver to use the new callbacks for hardware
programming. The first patch fixes an issue where cache value is
uninitialized during disable().
v2->v3:
* Prepared as a series.
* Created separate patch for fix for reinitialization of the cache
variable in disable().
* .round_waveform_tohw() do not fail if the requested period is too small
but use the smallest possible value.
* Added lock in rzg2l_gpt_read_waveform().
* wfhw is reinitialized in rzg2l_gpt_read_waveform if channel is disabled
* Optimizated rzg2l_gpt_is_ch_enabled() to avoid redundant reads to
RZG2L_GTCR(ch).
* .write_waveform() returns error incase of invalid period for second
channel.
