[U-Boot] [PATCH v2 1/7] bootcount: spl: Enable bootcount support in SPL

[Lukasz Majewski]

New, SPL related config option - CONFIG_SPL_BOOTCOUNT_LIMIT has been
added to allow drivers/bootcount code re-usage in SPL.

This code is necessary to use and setup bootcount in SPL in the case of
falcon boot mode.
