This patch adds support for incrementation of the bootcount in SPL. Such feature is necessary when we do want to use this feature with 'falcon' boot mode (which loads OS directly in SPL).

Changes in v4: - Use gd_t global data pointer instead of bootcount specific enum
Changes in v3: - Remove not needed #ifdefs - Add enum bootcount_context parameter to bootcount_inc() function
Changes in v2: - New patch - as suggested by Stefan Roese - bootcount_inc() is called in common SPL code (./common/spl/spl.c), so other boards can also reuse it without modification
