soc: nxp: lpc: lpc55sxxx: make clocks for peripherals depend on Kconfig
Make clock setup for each peripheral on the LPC55S69 dependent on if the Kconfig for that peripheral driver is enabled. This reduces the flash size of the LPC55S69 hello world image, since the code to setup these clocks no longer needs to run at boot. It also better mirrors how clocks will be setup within clock management, IE where each peripheral will setup its own clocks. Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>
