flash: add a driver for the internal flash on the SAM0 series. The SAM0 has a 64 byte page (the programing unit) with 4 pages to a row (the erase unit). This driver implements a read/modify/write to emulate the byte level writes used by NFFS. Signed-off-by: Michael Hope <mlhx@google.com>

Kconfig: Use a short, consistent style for prompts Consistently use config FOO bool/int/hex/string "Prompt text" instead of config FOO bool/int/hex/string prompt "Prompt text" (...and a bunch of other variations that e.g. swapped the order of the type and the 'prompt', or put other properties between them). The shorthand is fully equivalent to using 'prompt'. It saves lines and avoids tricking people into thinking there is some semantic difference. Most of the grunt work was done by a modified version of https://unix.stackexchange.com/questions/26284/ how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some of the rarer variations had to be converted manually.

subsys: storage: flash_map: enable only if any flash driver is enable It was possible to have enable flash module while no flash driver implementation was enabled. This cause coverity issues and unnecessary initialization call. This pat introduce FLASH_HAS_DRIVER_ENABLED Kconfig keyword which is selected once any flash driver is enabled. flash_map switch its dependency to this keyword.
