clk: imx6ull: use OSC clock during AXI rate change
[ Upstream commit 2e5be528ab0182ad4b42b9feea3b80f85f37179b ]
On i.MX6 ULL using PLL3 seems to cause a freeze when setting
the parent to IMX6UL_CLK_PLL3_USB_OTG. This only seems to appear
since commit 6f9575e55632 ("clk: imx: Add CLK_IS_CRITICAL flag
for busy divider and busy mux"), probably because the clock is
now forced to be on.
Fixes: 6f9575e55632("clk: imx: Add CLK_IS_CRITICAL flag for busy divider and busy mux")
