** [tickets:#353] Improper detection of flash banks/sizes for STM32L082CZ &
interface/stlink.cfg & target/stm32l0.cfg**

I'm flashing my STM32L082CZ using openocd -f interface/stlink.cfg -f
target/stm32l0.cfg and fail to program from the first bank onward into the
second flash bank. A number of ST's microcontrollers come with flash being two
banks, enabling booting one half or the other. But my programming fails at the
end of the first bank. Effectively I have only 96kb program flash available
(first bank only), rather than 192kb. Despite the banks being continuous in the
unified memory space.
Verification however does fail, so the verification is run properly over all
program bytes spanning both banks it appears.
Openocd does report (detect/probes) there being two banks (shows in the output)
but flash erase_sector 1 24 47 gives you flash bank 1 does not exist. Bit
confusing.
(Grep for the phrase "flash size will be probed" which will show up in
stm32l0.cfg)
There's already target/stm32l0_dual_bank.cfg which tries to work around it. But
it not fixes the probing but works around it?
