This commit implements 10/100 Mbit Ethernet support in the mimxrt port. The following boards are configured without ETH network: - MIMXRT1010_EVK - Teensy 4.0 The following boards are configured with ETH network: - MIMXRT1020_EVK - MIMXRT1050_EVK - MIMXRT1060_EVK - MIMXRT1064_EVK - Teensy 4.1 Ethernet support tested with TEENSY 4.1, MIMRTX1020_EVK and MIMXRT1050_EVK. Build tested with Teensy 4.0 and MIMXRT1010_EVK to be still working. Compiles and builds properly for MIMXRT1060_EVK and MIMXRT1064_EVK, but not tested lacking suitable boards. Tested functions are: - ping works bothway - simple UDP transfer works bothway - ntptime works - the ftp server works - secure socker works - telnet and webrepl works The MAC address is 0x02 plus 5 bytes from the manifacturing info field, which can be considered as unique per device. Some boards do not wire the RESET and INT pin of the PHY transceiver. For operation, these are not required. If they are defined, they will be used.
