[PATCH v3 0/3] Implement the watchdog timer of HiFive 1 rev b. |

The HiFive 1 rev b includes a watchdog module based on a 32-bit
counter. The watchdog timer is in the always-on domain device of
HiFive 1 rev b, so this patch added the AON device to the sifive_e
machine. This patch only implemented the functionality of the
watchdog timer, not all the functionality of the AON device.
You can test the patchset by the QTest tests/qtest/sifive-e-aon-watchdog-test.c
Changes since v1 ( Thank Alistair for the feedback ):
- Use the register field macro.
- Delete the public create function. The board creates the aon device itself.
- Keep all variable declarations at the top of the code block.
Changes since v2 ( Thank Alistair for the feedback ):
- Delete the declaration and definition of the create function.
