Add support of STM32L496xx/4A6xx devices

[homer242]

Hi,

I quickly added the support of my STM32L496G (discover) in stlink.

I can read and write data to the micro-controller memory. I think all is good.

Before write to the flash, I do a mass erase otherwise it fails with this message:

2017-07-14T15:48:32 ERROR src/common.c: Verification of flash failed at offset: 6144

Regards,

Thank you, you should associate your email adres (...@syscom-instruments.com) with your account which makes it easier for other people to look you up after merge.

Hi, thanks for adding support for STM32L496x. I have seen the similar "verification of flash" error on my STM32L496 Nucleo-144 device. This is the error.

2017-07-14T22:00:04 ERROR src/common.c: Verification of flash failed at offset: 4096

I have the fix for it and will file an issue and pull request.
