ARM: dts: da850-evm: add WP and CD to MMC

The legacy mode uses the write protect and card detect but DT does not. This patch enables Write-Protect and Card-Detect pins for the MMC card, and the gpio-ranges property sets the gpio pinmuxing for those respective pins.

V3: Update description of the patch. Rebase on davinci 4.18/dt
V2: Rebase on davinci master and remove GPIO pinmuxing
