Add CONFIG_LTO to use GCC Link-Time Optimizations to try to reduce the
flash footprint of the firmware.
Add additional protection to some functions/data to avoid removal by the
linker when their usage is not obvious.

Sometimes the toolchain tries to put a relocation which is not suitable
to access variables in a read-only section.
The nds32 gcc uses GP-relative signed 17-bit relocation to access
variables stored in .rodata (eg lwi.gp $r0, [ +gp ])
That's wrong since $gp is pointing in the middle of .data and .bss in
the SRAM, while .rodata is sitting in flash.
Since on IT8380, the flash is at 0x00000 and the SRAM is at 0x80000
(512kB further), the linker will fail trying to create the signed 17-bit
relocation (it detect that it needs to truncate it)
Force the compiler to put another relocation as a workaround for now.

This is tidier than every board defining its own module_id enum, and
encourages standard naming of modules.
A subsequent CL will do more cleanup (standardizing on MODULE_LED
instead of MODULE_POWER_LED and MODULE_LED_KIRBY), but it's easier to
do that as a separate CL than part of this one.

To create a token by concatenating already-defined macros and new

done that in several places in the code such as STM32_CAT; this now
