For example, memory-region in .dts as below,
reg = <0x0 0x5000 0x0 0x2000>
We can get below values,
struct resource r;
r.start = 0x5000;
r.end = 0x6fff;
So the size should be:
size = r.end - r.start + 1 = 0x2000

Some of DP link compliant test expects to return fail-safe mode
if prefer detailed timing mode can not be supported by mainlink's
lane and rate after link training. Therefore add fail-safe mode
into connector mode list as backup mode. This patch fixes test
case 4.2.2.1.

DP driver is a generic driver which supports both eDP and DP.
For debugging purpose it is required to have capabilities to
differentiate message are generated from eDP or DP. This patch
add connector type into debug messages for this purpose.
