mx6: clock: Fix the logic for reading axi_alt_sel
According to the IMX6DQRM Reference Manual, the description
of bit 7 (axi_alt_sel) of the CCM_CBCDR register is:
"AXI alternative clock select
0 pll2 396MHz PFD will be selected as alternative clock for AXI root clock
1 pll3 540MHz PFD will be selected as alternative clock for AXI root clock "
The current logic is inverted, so fix it to match the reference manual.
