flash/stm32l4x: add support of STM32WLEx devices
STM32WLEx devices are based on arm Cortex-M4 running at 48MHz,
contains a single bank of maximum 256 Kbytes of flash memory.
there is 3 variants with different Flash/RAM sizes:
STM32WLE5JC : 256K/64K
STM32WLE5JB : 128K/48K
STM32WLE5J8 : 64K/20K
the work-area size is set to 20 kb to fit in STM32WLE5J8
