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.
