stm32/make-stmconst.py: Fix missing peripheral consts in stm module.

Lines like the following were not handled by `make-stmconst.py`:

    #define APBPERIPH_BASE        (PERIPH_BASE)

This leads to missing definitions on stm module.  For example, `stm.RTC` is
not defined if `RTC_BASE` is defined as

    #define RTC_BASE              (APBPERIPH_BASE + 0x00002800UL)

because `APBPERIPH_BASE` is not handled as a valid id.

This patch modifies the RegExp so it can handle the above.
