We mod #BL602 #NuttX to set the GPIO Output Enable Register at 0x40000190 (BL602_GPIO_CFGCTL34)

#BL602 IoT SDK says that GPIO Output Enable Register is at 0x40000190 (GLB_GPIO_CFGCTL34) ... Let's set this register in #NuttX

#BL602 Reference Manual says we should set the GPIO Output Enable Register ... But it's missing from the docs ... Where is the register? 🤔

#NuttX configures #BL602 GPIO 11 (0x40000114) with GPIO Input Disabled ... But it doesn't Enable GPIO Output 🤔

#NuttX writes correctly to the GPIO 11 Output Register at 0x40000188 (BL602_GPIO_CFGCTL32)
