ARMCM3-STM32L152RE-NUCLEO demo

[delay]

Hi,
I have a NUCLEO-L152 board which does not have the external oscillator. In order for the demo to work, a definition must be set in mcuconf.h:53
#define STM32_RTCSEL STM32_RTCSEL_LSI

But the thing is that when I tried to build the demo, it failed because it was defined as STM32_RTCSEL_LSE (external oscillator). So if there is a version of the NUCLEO-L152 with external oscillator, it must be enabled at mcuconf.h:40.

Probably internal oscillator is the safest choice for the demo.

Moved to the STM32 section, I will fix the demo, thanks.
