riscv: dts: eswin: add I2C controller support

This commit adds I2C nodes for the EIC7700 SoC and enables corresponding
slave devices for the HiFive Premier P550 board.

[Severity: High]
Should this use the AON pins (&i2c10_pins) instead of the LSP pins?

Assigning &i2c0_pins here configures the pads for the Low Speed Peripheral
i2c0 controller, leaving the AON I2C bus disconnected from the external
pads and preventing communication with the EEPROM.

[Severity: High]
Similarly, should this use &i2c11_pins for the aon_i2c1 controller?

Routing the AON controller to the LSP i2c1 pins will cause the ADC and
power sensor to fail on boot due to being physically disconnected.
