In meson_pinctrl_parse_dt, it contains two parts: reg parsing and
SoC relative fixup for AO. Several fixups in the same code make it hard
to maintain, so move all fixups to each SoC's callback and make
meson_pinctrl_parse_dt just do the reg parsing, separate these two
parts.Overview of all current Meson SoCs fixup is as below:

+------+--------------------------------------+--------------------------+
|      |                                      |                          |
| SoC  |                EE domain             |        AO domain         |

|gxbb  |   no                                 |     pull-enable = pull;  |
|axg   |                                      |                          |
+------+--------------------------------------+--------------------------+

|      |                                      |   pull-enable = gpio;    |

|a1 or | parse regs:                                                     |
|later |  gpio/mux (without ao domain)                                   |
|SoCs  | fixup:                                                          |
|      |  pull = gpio; pull-enable = gpio; ds = gpio;                    |
+------+-----------------------------------------------------------------+
Since m8-axg share the same ao fixup, make a common function
meson8_aobus_parse_dt_extra to do the job.
