imxrt: add support for rt1050

This change splits 10xx into 106x (copy) and extracts 105x. Modules such
as otp.c, console.c, timer.c and others come from the common 10xx
implementation, config.h, init.S and imxrt.[ch] hal are dedicated
separately for 105x and 106x.

The linker script for rt105x target have been adapted to the FlexRAM
configuration as follows: ITCM = 160 KiB, DTCM = 288 KiB, OCRAM = 64 KiB,
and FLASH = 8 MiB.

Because it carries code that was already implemented, it does not
introduce fixes related to MISRA
