Currently, drive-strenght to 12ma are described and supposed to be used
on RK3288. However, the pinctrl driver for this SoC only handles muxing
and pull up/pull down via PU/PD control registers. So complex IPs like
GMAC are working in normal ethernet 100mbps, but not at 1gbps typically.
This commit adds support for handling drive-strength of 12ma, when it's
defined in the DT.

This function returns the pointer to the value of a node property.
The current name ofnode_read_prop() is confusing. Follow the naming
of_get_property() from Linux.
The return type (const u32 *) is wrong. DT property values can be

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
