There is no need to call the dev_err_probe() function directly to print
a custom message when handling an error from platform_get_irq_byname()
function as it is going to display an appropriate error message
in case of a failure.

Due to a silicon bug, ESM on TPS6594 PMIC revision 1 is not working
properly. This patch keeps SOC ESM disabled for such PMIC.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
There are two calls that can go wrong in tps6594_esm_remove(); for both
there is already an error message. Not returning the error code has the
only side effect of suppressing (another) error message by the core
about the error being ignored. So tps6594_esm_remove() can be converted
to return void without any loss.

This patch adds support for TPS6594 ESM (Error Signal Monitor).
This device monitors the SoC error output signal at its nERR_SOC input pin.
In error condition, ESM toggles its nRSTOUT_SOC pin to reset the SoC.
