[ethernet] Add DM9051 support

Browse source 
Fixes https://github.com/esphome/feature-requests/issues/2427

Tested on an ETH01-Evo board using

  ethernet:
    type: DM9051
    clk_pin: GPIO07
    mosi_pin: GPIO10
    miso_pin: GPIO03
    cs_pin: GPIO09
    interrupt_pin: GPIO08
    reset_pin: GPIO06
    clock_speed: 20MHz

A number of read errors was observed with 26 MHz
(default) or higher clock speeds. This might be a
board specific problem.
