net: hisilicon: Add Fast Ethernet MAC driver

This patch adds the Hisilicon Fast Ethernet MAC(FEMAC) driver.
The FEMAC supports max speed 100Mbps and has been used in many
Hisilicon SoC.

Hisilicon Fast Ethernet MAC controller
Required properties:
- compatible: should contain one of the following version strings:
* "hisilicon,hisi-femac-v1"
* "hisilicon,hisi-femac-v2"
and the soc string "hisilicon,hi3516cv300-femac".
- reg: specifies base physical address(s) and size of the device registers.
The first region is the MAC core register base and size.
The second region is the global MAC control register.
- interrupts: should contain the MAC interrupt.
- clocks: A phandle to the MAC main clock.
- resets: should contain the phandle to the MAC reset signal(required) and
the PHY reset signal(optional).
- reset-names: should contain the reset signal name "mac"(required)
and "phy"(optional).
- mac-address: see ethernet.txt [1].
- phy-mode: see ethernet.txt [1].
- phy-handle: see ethernet.txt [1].
- hisilicon,phy-reset-delays-us: triplet of delays if PHY reset signal given.
The 1st cell is reset pre-delay in micro seconds.
The 2nd cell is reset pulse in micro seconds.
The 3rd cell is reset post-delay in micro seconds.
