2020-07-17x86: apl: Fix save/restore of ITSS prioritiesSimon Glass
The FSP-S changes the ITSS priorities. The code that tries to save it before running FSP-S and restore it afterwards does not work as U-Boot relocates in between the save and restore. This means that the driver data saved before relocation is lost and the new driver just sees zeroes. Fix this by allocating space in the relocated memory for the ITSS data. Save it there and access it from the driver after relocation. This fixes interrupt handling on coral. Also drop the log_msg_ret() in irq_first_device_type() since this function can be called speculatively in places where we are not sure if there is an interrupt controller of that type. The resulting log errors are confusing when there is no error.
