STLINK-V3 and the new firmware V2J24 for ST-LINK/V2 provide API to directly access the DAP registers. This mode permits to use the native target in cortex_m.c, with no need to override it with the target in hla_target.c. Other advantages wrt HLA are: support for Cortex-A cores, support for SoC multi-core and/or multi AP, support for OpenOCD commands "dap" thus including control of CSW. This obsoletes the existing HLA driver for ST-Link, that should anyway be kept for those cases where it's not possible to update the ST-Link firmware. This commit introduces the minimal implementation for direct DAP access. The implementation is much slower than the HLA because every memory transfer requires several USB packets. Further commits will close the performance gap. The whole ST-Link driver is compiled under BUILD_HLADAPTER, to remove the need to split the driver between the two modes. This has to be reworked, but it's quite invasive! A new interface file stlink-dap.cfg is added and should be used in place of stlink.cfg to enable the DAP mode. Documentation is updated and reports limitation on the maximum AP number that can be accessed by ST-Link for some firmware already tested.
