hw/arm/boot: Make user not specifying a kernel not an error 

Typically ARM boards will have some kind of flash which might contain
a boot ROM; it's therefore a valid use case to provide only an
image for the boot ROM and not require QEMU's internal boot loader
at all. Remove the fatal error if -kernel isn't specified.
