Hi:
  In the development work, we found that some of the previous
incorrect clock configuration on the RK3036 platform, we should
fix them.

Message-ID<qOhHR-7YB-29@gated-at.bofh.it>
In reply to#1303522
Due to reference to old version TRM, there are incorrect emac clock node.
The SEL_21_9 is used for the parent div, the SEL_21_4 is used for the
child div.

The DFLAGS are used for the clock dividers, the CLKSEL_CON flags
of COMPOSITE_NODIV type should be MFLAGS.

There is only support rmii in the RK3036, so we should use the correct
ext clock name.

We need to add HCLK_MAC id explicitly because that it is referred
by hclk in the emac driver.

I've applied patches 1-4 as fixes for 4.5 [0] and will apply patch 5
regularly once 4.5-rc1 is released and I have stable base again.

please make sure to also update the binding document in such cases.
I've done it myself for this one.

[for people reading along: the rk3036 clock-driver + binding is new in
4.5 so we should be ok to fix the naming before it is actually released]
