ARM: dts: Add wlcore wakeirq for omap3-evm
With wlcore supporting optional wakeirqs, let's configure it for omap3-evm and update the related pin muxing as some pins are left unmuxed. Let's configure a wakeirq both for the wlcore GPIO and the SDIO dat1 pin in case wlcore starts supporting SDIO dat1 interrupt at some point. Note that for off-mode, the wlcore reset GPIO will have a glitch meaning wlcore will reset. The only way to workaround for this currently is to configure the reset pin with SAFE_MODE + PULL.
