regulator: Switch i2c drivers back to use .probe() After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

regulator: slg51000: Wait after asserting CS pin Sony's downstream driver [1], among some other changes, adds a seemingly random 10ms usleep_range, which turned out to be necessary for the hardware to function properly on at least Sony Xperia 1 IV. Without this, I2C transactions with the SLG51000 straight up fail. Relax (10-10ms -> 10-11ms) and add the aforementioned sleep to make sure the hardware has some time to wake up.

regulator: slg51000: switch to using fwnode_gpiod_get_index devm_gpiod_get_from_of_node() is being retired in favor of [devm_]fwnode_gpiod_get_index(), that behaves similar to devm_gpiod_get_index(), but can work with arbitrary firmware node. It will also be able to support secondary software nodes. Let's switch this driver over. Note that now that we have a good non-devm API for getting GPIO from arbitrary firmware node, there is no reason to use devm API here as regulator core takes care of managing lifetime of "enable" GPIO and we were immediately detaching requested GPIO from devm anyway.

regulator: slg51000: use devm_gpiod_get_optional() in probe The CS GPIO line is clearly optional GPIO (and marked as such in the binding document) and we should handle it accordingly. The current code treats all errors as meaning that there is no GPIO defined, which is wrong, as it does not handle deferrals raised by the underlying code properly, nor does it recognize non-existing GPIO from any other initialization error. As far as I can see the only reason the driver, unlike all others, is using OF-specific devm_gpiod_get_from_of_node() so that it can assign a custom label to the selected GPIO line. Given that noone else needs that, it should not be doing that either. Let's switch to using more appropriate devm_gpiod_get_optional().
