[RESEND 0/7] Refactor generic fastboot_set_reboot_flag implementation

[Roman Kovalivskyi <roman.kovalivskyi@globallogic.com>]

Current generic implementation of fastboot_set_reboot_flag is somewhat
messy and requires some additional configuration option to be enabled
besides CMD_BCB, so it reverts that implementtion in order to bring a
new cleaner one.

New function called bcb_set_reboot_reason should be exposed by BCB
commands, so that all of the details could be put there instead of
dealing with it in fastboot implementation directly. After that,
fastboot_set_reboot_flag could simply pass correct reboot reason
string to the BCB implementation. If CMD_BCB is disabled then the
whole operation would return error code, which is no different
behaviour than the current implementation.

Eugeniu Rosca (5):
  cmd: bcb: Extract '__bcb_load' from 'do_bcb_load' for internal needs
  cmd: bcb: Extract '__bcb_set' from 'do_bcb_set' for internal needs
  cmd: bcb: Extract '__bcb_store' from 'do_bcb_store' for internal needs
  cmd: bcb: Expose 'bcb_write_reboot_reason' to external callers
  cmd: bcb: Add support for processing const string literals in
    bcb_set()

Roman Kovalivskyi (2):
  Revert "fastboot: Add default fastboot_set_reboot_flag implementation"
  fastboot: Implement generic fastboot_set_reboot_flag
