Platform: Extend NV counter interface

This patch adds the tfm_plat_set_nv_counter() function to the NV counter
interface for supported platforms: AN521, AN519, Musca-A and Musca-B1.
To set a NV counter to a specified value can take a lot of time and
leads to early flash wear out when incrementing the counter by one.
