dm: core: Inline a few ofnode functions in SPL
A recent change to unify the flattree/livetree code introduced a small
size increase in SPL on some boards. For example SPL code size for
px30-core-ctouch2-px30 increased by 40 bytes.
To address this we can take advantage of the fact that some of the ofnode
functions are only called a few times in SPL, so it is worth inlining
them.
Add new Kconfig options to control this. These functions are not inlined
for U-Boot proper, since this increases code size.
Fixes: 2ebea5eaebf ("dm: core: Combine the flattree and livetree binding code")
