ae3xx: timer: Rename AE3XX to ATCPIT100
ATCPIT100 is Andestech timer IP which is embeded in AE3XX and AE250 boards. So rename AE3XX to ATCPIT100 will be more make sence. Signed-off-by: rick <rick@andestech.com> Signed-off-by: Rick Chen <rickchen36@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
