stm32l1: rcc/lcd: fix RTCSEL HSE definition

Browse Source 
Wrong since original commit in 2013.

LCD code can't actually automatically determine clock speed if it's HSE,
as we don't know here whether what HSE is, nor what it's divided by.
For more fun, that old 2014 API doesn't have any way of flagging that it
failed either.  Hooray.
