[U-Boot] [PATCH v3 1/6] board_f: Drop the timer after relocation

[Simon Glass]

Once U-Boot relocates itself the existing driver-model timer (if any) is
no-longer valid until the device is reinitialised. Any use of the device
may cause a crash. To handle this, set the timer to NULL after relocation.
