Simon Glass a1b17e4f4c dm: core: Add a function to read into a unsigned int ...

The current dev_read...() functions use s32 and u32 which are convenient
for device tree but not so useful for normal code, which often wants to
use normal integers for values.

Add a helper which supports returning an unsigned int. Also add signed
versions of the unsigned readers.
