cc3200: Move pinmux and UART initialization to PRE_KERNEL_1

Browse source 
Previously, cc3200_launchxl board was not able to show the
Zephyr Boot Banner, as that required early initialization
of the UART driver, which was done POST_KERNEL.

This patch moves the pinmux and UART driver initialization
to PRE_KERNEL_1, allowing early printk, and the Boot Banner
to show.
