bootloader: avoid printing load addresses with '0x'

Since idf_monitor decodes anything that looks like a code address and
starts with 0x, bootloader logs often get annotated with function
names such as WindowOverflow and other random and scary looking things
unrelated to the issue the user is facing. Print the addresses without
0x to avoid confusion by decoded function names. Print hexadecimal
size with 'h' suffix to distinguish it from the decimal value that
follows.
