[edk2-platforms][PATCH V1 1/1] Platform/Intel/Readme.md: Content update

["Kubacki, Michael A" <michael.a.kubacki@intel.com>]

This change makes the following updates:
 1. Indicate that build via batch scripts is no longer allowed.
 2. Remove ClevoOpenBoardPkg batch build instructions since
    the batch build scripts no longer exist in the package.
 3. Move firmware image flashing instructions to a clearly labeled
    section.
 4. Elaborate the firmware image flashing instructions.

+### **Firmware Image Flashing**
+
+The full Intel firmware image on a flash device is called the Integrated Firmware Image (IFWI). Users with access to the Intel
+proprietary FITC tool and ME ingredients can build full IFWI images that may be flashed (Descriptor, UEFI FW, ME FW, etc.).
+
+Users without such access can directly flash a custom built UEFI FW image over the highest area of the flash region directly.
+It is always recommended to have a hardware flash programmer accessible to recover the firmware image. The original full flash
+image should always be backed up so it may be flashed again for recovery. Please be aware that if a system supports a technology
+that authenticates the initial firmware boot image such as Boot Guard, it will fail to boot with a custom firmware image
+that is not signed properly.
+
 ### **Planned Activities**
 * Replace the batch build scripts with cross-platform Python build scripts.
 * Publish a Minimum Platform specification to describe the architecture and interfaces in more detail.
