If a machine doesn't have CONFIG_CLK set the call to clk_get_bulk() returns '-ENOSYS' error which should be handled the same way as '-ENOENT' error. The same applies to reset_get_bulk() and 'ENOTSUPP'.

Signed-off-by: Piotr Wojtaszczyk piotr.wojtaszczyk@timesys.com --- Changes for v3: - Removed extra parenthesis around error checks

Changes for v2: - Changed logic style from !(== || ==) to (!= && !=)
