clk: imx: keep hsio bus clock always on
During Linux System suspend/resume stress test after System Sleep
enabled, system will stuck sometimes. It is because NICMIX is powered
down, which HSIOMIX(always on) is not powered down. When NICMIX
powering down, HSIOMIX will get a hardware handshake, without HSIO ROOT clk,
the handshake will lose. Then after NICMIX power on when system resume,
the access to HSIOMIX through NICMIX would be broken. So keep HSIO ROOT
always on.
