[PATCH 5.4 336/389] clk: rockchip: add sclk_mac_lbtest to rk3188_critical_clocks

[Greg Kroah-Hartman]

From: Alex Bee <knaerzche@xxxxxxxxx>

commit ef990bcad58cf1d13c5a49191a2c2342eb8d6709 upstream.

Since the loopbacktest clock is not exported and is not touched in the
driver, it has to be added to rk3188_critical_clocks to be protected from
being disabled and in order to get the emac working.
