meta: introduce UBOOT_MKIMAGE_KERNEL_TYPE

Sometimes an end user might want to choose another kernel type argument
for uboot-mkimage other than "kernel", for instance: "kernel_noload".

Let's introduce a variable UBOOT_MKIMAGE_KERNEL_TYPE to support that,
and it could be used by BSP layers as well.
