flash/stm32*: Sync all device/rev IDs with reference manuals

Uppercase device/family names and change them to be more specific and
consistent across all STM32 families.

High-density STM32F10x has a Rev Y according to RM0008 Rev 14, so add
it.

I have a STM32F30x Rev Y, sitting on my desk, but it isn't described in
the reference manual. Add it as well.

Split the STM32L1xx Medium+ Density devices based on ID, to match the
reference manual. If I read it correctly, the Medium+ devices have
different revision mappings depending on their package/device ID. I have
no real devices to examine, however.
