boards: frdm_rw612: Simple enablements collection
A collection of simple enablements to match some of the enablement done for rd_rw612_bga as closely as possible on the frdm_rw612 board. - i2c - spi - dma - mrt - ctimer - os timer - dac - adc - trng (alread was enabled but now listed support) - watchdog Signed-off-by: Declan Snyder <[email protected]>
