Loads of general and MIMXRT-specific test fixes (ARMmbed#412)

* Update MIMXRT105x linker script to use memory banks

* Disable SRAM for now :/

* Add split heap support

* Loads of general and MIMXRT-specific test fixes

* Style fix

* Remove include guard from mbed_config.tmpl so that it can be re-included by the build system

* Oops left that line there
