[PATCH v3 0/1] CMD commands improvements
- add ability for 'ums' command to interrupt run of usb mass storage with any key. This is especially useful on devices with limited input capabilities like tablets and smatphones which have only gpio keys in direct access. Current implementation uses Kconfig entry.
Changelog from v2 - fix stuck of ums due to getchar loop. Now getchar is called after tstc check.
Changelog from v1 - 'continue' command commit was dropped as there already exists 'pause' command with same function. - UMS_ABORT_KEYED renamed to CMD_UMS_ABORT_KEYED
