clk: Add devm_clk_bulk_get_enable()

Browse source

devm_clk_bulk_get_optional_enable() gets, prepares and enables a set of
clocks with device-managed cleanup, but treats every clock as optional:
a missing clock is silently returned as NULL instead of failing.

Consumers that need a fixed set of mandatory clocks enabled for the
lifetime of the device currently have to open-code devm_clk_bulk_get()
followed by clk_bulk_prepare_enable(), which loses the managed disable on
unbind, or fall back to per-clock devm_clk_get_enabled() calls.

Add devm_clk_bulk_get_enable() as the non-optional counterpart. The
underlying __devm_clk_bulk_get_enable() helper already supports the
required (optional = false) path, so only export a thin wrapper for it.
