Add CONFIG_BOOTCOUNT_ALTBOOTCMD so the developer is able to add custom altbootcmd via Kconfig when they enable BOOTCOUNT. With this now in Kconfig, we need to move it from environment files / config.h files and in to the defconfig file. This was done by generating u-boot-initial-env for all platforms before the Kconfig change, to extract altbootcmd values and then again after to compare the result.

If there is upgrade in software then "upgrade_available" is 1,

"bootcount" is incremented otherwise "upgrade_available" and

"bootcount" is always 0. So the Userspace Application must set

the "upgrade_available" and "bootcount" variable to 0, if a boot

was successfully.
