NUMAKER_PFM_M2351 doesn't compile with GCC, ARMC5, IAR

[MarceloSalazar]

Description

I've tested the mbed-os-example-blinky example application with latest Mbed OS (5.13.3 at this time).

The mbed tools show:

• Target NUMAKER_PFM_M2351 is not supported by toolchain GCC_ARM
• Target NUMAKER_PFM_M2351 is not supported by toolchain IAR
• Target NUMAKER_PFM_M2351 is not supported by toolchain ARMC5

However, these toolchains have to be supported to be compliant with Mbed Enabled

I believe this is the only target with an exception.

@ARMmbed/team-nuvoton When IAR and GCC ARM are going to be supported?

Toolchain support on M2351:

• ARMC5 doesn't support ARMv8M, so it is excluded. Support ARMC6 instead.
• GCC support has been on-going. It is not enabled because there's something wrong in GCC-compiled secure function code.
• IAR support is not scheduled currently. Maybe after M2351: Support TFM level 1 #10959 lands so that related changes can be clear.

Closing as the m2351 is not enabled in master for Mbed OS 6.0.
We'll retest when reintroduced. It will have to work with gcc 9 and arm compiler 6.
