You can even do those two as well :)

and all the others in this file :) I would recommend to only do for 
those that start with CONFIG_ which are Kconfig symbols. E.g. 
PHYS_SDRAM_2_SIZE isn't, so I don't think you can use IS_ENABLED.

The easiest way to check everything is fine is to compile before and 
after patching the file and checking that the output is bit to bit 
identical (you may need to change the SOURCE_DATE_EPOCH to guarantee 
that though?

A change like that would just be code churn and I'd rather not see it.
Especially since yes, you *can* get away with IS_ENABLED(FOO) and the
kernel does it in a few places, but you shouldn't do that in U-Boot as
it's more likely to be an error (you wanted IS_ENABLED(CONFIG_FOO)) than
a helpful case of:
        if (IS_ENABLED(FOO)) { ... }
