rockchip: mkimage: force 2KB alignment for init_size

Browse Source 
The Rockchip BootROM relies on init_size being aligned to 2KB
(see https://lists.denx.de/pipermail/u-boot/2017-May/293268.html).

This pads the image to 2KB both for SD card images and SPI images
and uses a common symbolic constant for the alignment.
