Today the bootcount is not managed by the Linux kernel for STM32MP15 as we don't have driver to update the used backup register in TAMP and the recovery command still executes the normal bootcmd with 'altbootcmd=run bootcmd'. So the bootcount feature is never used, the config CONFIG_BOOTCOUNT_LIMIT and the associated environment variable 'altbootcmd' can be removed to reduce the U-Boot size. Each boards can re-enable this feature later in their defconfig, if it is needed, with the expected backend, for example CONFIG_BOOTCOUNT_GENERIC or CONFIG_BOOTCOUNT_ENV.
