linux:imx8m: Remove the in-kernel PCF8563 driver
Because we store some boot information (bootselect) data in the PCF8563 we need to modify the driver in a way that it does not reset the RTC registers. However, we do not want to pus this into the kernel so we decided to create an out-of-tree fork.
Then, however, both drivers the in-kernel and out-of-tree driver conflicting each other, and thus remove the former one.
