[PATCH v2 4/4] clk: Drop obsolete devm_clk_bulk_get_all_enable() helper

Commit 265b07df758a ("clk: Provide managed helper to get and enable bulk
clocks") added devm_clk_bulk_get_all_enable() function, but missed to
return the number of clocks stored in the clk_bulk_data table referenced
by the clks argument. Without knowing the number, it's not possible to
iterate these clocks when needed, hence the argument is useless and
could have been simply removed.

A new helper devm_clk_bulk_get_all_enabled() has been introduced, which
is consistent with devm_clk_bulk_get_all() in terms of the returned
value.

Drop the obsolete function since all users switched to the new helper.
