[U-Boot] ahci: Fix cache align error messages

[Eli Nidam]

Hi Roger,

I used the definition CONFIG_SYS_DCACHE_OFF (in our u-boot the cache is off)

For this reason I didn't get this message.

Thanks

Eli

You are right. My patch is all messed up and better to revert it, sorry.

Do you still get the below messages after the revert?

ERROR: v7_dcache_inval_range - start address is not aligned - 0xfee46648
ERROR: v7_dcache_inval_range - stop address is not aligned - 0xfee46848
