h1x0/h300: clean up the bootloader source a bit

First this removes most of the conditionals for the CPP as they
are always true for the targets that use the bootloader source.

Second this moves some global variable references around to reduce
some redundancy in the h1x0 bootloader source.

All of this is done to make it easier to compare the two bootloaders
as they are very heavily related to each other.
