boards: arm: cy8ckit_062_ble: Add serial pinctrl and int

Add pinctrl and interrupt information for both m0/4 cores. The uart-5 is the default serial communication on the kit and it is connected to Cortex-M0+ cpu. It uses SCB[5] and the NVIC line 21 as interrupt source on Cortex-M0+ cpu. The line 21 is an arbitrary value and users can select any value. The SCB[5] shares pins with Arduino headers D0/D1 and it is wired with the on-board USB Serial converter. This means, if use wants use an external shield it must rework the board. The uart-6 is the default serial communication for Cortex-M4 cpu, which uses SCB[6]. Signed-off-by: Gerson Fernando Budke <[email protected]>
