Warnings when building 3.0.0 release with -pedantic

[aescolar]

When building in a project with -pedantic and the latest release,

There is now lot's (thousands) of warnings akin to:

nrfx/hal/nrf_spim.h:134:1: warning: ISO C99 requires at least one argument for the "..." in a variadic macro
134 | #if NRFX_FEATURE_PRESENT(SPIM, _FEATURE_RXDELAY_PRESENT) || defined(__NRFX_DOXYGEN__)
     | ^~~~~~~~~~~~~~

nrfx/hal/nrf_egu.h:298:1: warning: ISO C99 requires at least one argument for the "..." in a variadic macro
  298 |     NRF_INTERNAL_EGU_CHAN_NUM_EXTRACT(chan_num, p_reg);
      | ^   ~~~~~~~~~~

They all seem to boil down to the same issue:
