flash/stm32l4x: zero init stm32l4_flash_bank struct on flash bank initialization

This is specially needed when, in the probe routine, device is not
found among the stm32l4_parts. In this case, the stm32l4_flash_bank->part_info
is undefined and inadvertentanly used afterwards:
part_info = stm32l4_info->part_info;

If the stm32l4_flash_bank is zero init, the probe routine checks for
the validity of the part_info field in the previous struct and correctly
detects the unsupported (or not found) condition, raising an error
rather than a SIGSEGV
