Add support for MIMXRT1170-EVK and MIMXRT1060-EVK boards

[mbrossard]

Builds on #904 PR.

MIMXRT1170-EVK work initially done by @nxpyandld and @groleo (with CMSIS-DAP 2.1 refresh added).

In #712, @groleo wrote about the changes in source/family/freescale/target_reset_mimxrt.c:

From what I understand, if buf is a FlexSPI Config block (the "FCFB"/0x42464346 test), it moves the flash start
address; but I have no idea what the test against 0xFFFFFFFF part does; I see some other platforms have a
"cookieList"

@nxpyandld, @groleo, @flit: Is that something that will interfere with other i.MX RT targets?

The 0x400 offset comes from the "Image Vector Table Offset and Initial Load Region Size" table in the Reference Manual. I have not found where the 0xFFFFFFFF comes from.
