The i.MX fixes for 3.18, 2nd round:
- Fix a regression on Vybrid platform which is caused by commit dc4805c2e78b (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3
driver), and results in a missing configuration on PLL clocks.
- Fix a regression with i.MX defconfig files where CONFIG_SPI option
gets lost accidentally.
