regulator: qcom_spmi: Keep trying to add regulators if read fails
On some designs, a handful of the regulators can't be read via
SPMI transactions because they're "secure" and not intended to be
touched by non-secure processors. This driver unconditionally
attempts to read the id registers of all the regulators though,
leading to probe failing and no regulators being registered.
Let's ignore any errors from failing to read the registers and
keep adding other regulators so that this driver can probe on
such devices.
