aae877dbf2 mkimg: adjust flashable image size
* It's been reported that 14848MiB = 15569256448 bytes is still too
  large to fit some 16GB storage devices.
* 15360000000 bytes is dividable by 16384, 4096, 2048, 1024, 512, ...
* Fixes 0151cc35c1.

3013eb147b set hardware platform name
* Some hardware information applications use this so set actual hardware
  platform name.
* Historic reason why this was set to rpi is that this allowed to use same
  HALs on rpi3/rpi4 when they were commonized. 'ro.board.platform' this sets
  is used in the legacy module load order.
  https://android.googlesource.com/platform/hardware/libhardware/+/refs/tags/android-15.0.0_r20/modules/README.android
  This has no use with modern HIDL/AIDL/APEX HALs. For legacy HALs name can
  be implicitly set using system properties (e.g. 'ro.hardware.audio.primary'
  that's still relevant).
