[U-Boot] [PATCH v5 5/7] bootcount: spl: Extend SPL to support bootcount incrementation

[Lukasz Majewski]

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 v5:
- None

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
