[PATCH v2 3/7] rockchip: px30: Add EVB_PX30 Kconfig help

[Suniel Mahesh]

From: Jagan Teki <jagan at amarulasolutions.com>

TARGET_EVB_PX30 can be possible to use other px30 boards.

Add the help text for existing EVB, so-that the new boards
which are resuing this config option can mention their board
help text.

This would help to track which boards are using EVB_PX30 config.
