This patch adds QSPI boot support for LS2080AQDS board. The QSPI boot image need to be programmed into the QSPI flash first. Then we can switch to booting from QSPI memory space.

Yuan,
Do you think you can reorder these patches so that early i2c init can be in front of disabling IFC? Then you don't have to use fixed clk at all. I am thinking if we run git bisect and this set could break QSPI boot if sys clk is other than 100MHz.
Sorry for the mistake, it's a good suggestion. I will resend the patch soon. Thanks for your review.
