[msom] Fix ethernet cs, reset, interrupt GPIO pins for M2 eval

[scott-brust]

Problem

GPIO pins for ethernet on msom platform were not updated to match M2 eval board pinout

Solution

Fix it

Steps to Test

Enable ethernet feature

System.enableFeature(FEATURE_ETHERNET_DETECTION);

Reset and try ethernet on M2 eval

Example App

Use snippet to print ethernet configuration / state

auto conf = Ethernet.getConfig();
uint8_t ethernet_mac[6] = {};
Ethernet.macAddress(ethernet_mac);
Log.info("MAC: %02X:%02X:%02X:%02X:%02X:%02X",
    ethernet_mac[0],ethernet_mac[1],ethernet_mac[2],
    ethernet_mac[3],ethernet_mac[4],ethernet_mac[5]);


Log.info("localIP: %s", Ethernet.localIP().toString().c_str());
Log.info("DHCP: %s", Ethernet.dhcpServerIP().toString().c_str());
Log.info("Gateway IP: %s", Ethernet.gatewayIP().toString().c_str());
Log.info("Subnet Mask: %s", Ethernet.subnetMask().toString().c_str());


for (const auto& addr: conf.addresses()) {
    Log.info("Addr: %s/%u (%s) - family = %d", addr.address().address().toString().c_str(), (unsigned)addr.prefixLength(), addr.mask().address().toString().c_str(), addr.family());
}
for (const auto& addr: conf.dns()) {
    Log.info("DNS: %s", addr.toString().c_str());
}
Log.info("Gateway: %s", conf.gateway().toString().c_str());
Log.info("Source: %d/%d", (int)conf.source(AF_INET), (int)conf.source(AF_INET6));
