rtc: jz4740: make the driver buildable as a module again
By using kernel_halt() instead of machine_halt(), we can make the driver build as a module. However, jz4740 platforms not loading this module will not be able to power off. Suggested-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Revert "rtc: jz4740: make the driver builtin only" This reverts commit b9168c539c0b2de756aaffd380384dbde8adbe07.
