[PATCH] dt-bindings: pinctrl: spacemit: fix drive-strength check warning

[Yixun Lan]

The problem is that one value from drive-strength may match to more than
two different enum groups which lead to DT complaint, switch to use 'anyOf'
to fix this kind warning.

Fixes: c3efac0592f8 ("dt-bindings: pinctrl: spacemit: convert drive strength to schema format")
Signed-off-by: Yixun Lan <dlan@kernel.org>

Doing DT check with command: make dtbs_check W=1, will get this kind
of warning message:

arch/riscv/boot/dts/spacemit/k1-musepi-pro.dtb: pinctrl@d401e000 (spacemit,k1-pinctrl): gmac0-cfg:gmac0-pins:drive-strength: 21 is valid under each of {'enum': [2, 4, 6, 7, 9, 11, 13, 14, 21, 23, 25, 26, 28, 30, 31, 33]}, {'enum': [11, 21, 32, 42]}

Instead of using more complicated minimum and maximum value of property
with constrains of compatibles, we decide to use 'anyOf' to fix this
warning.
