[PATCH v2 2/4] riscv: dts: anlogic: dr1v90: Add "b" ISA extension

"b" is ratified (Apr/2024) much later than its components zba/zbb/zbs
(Jun/2021). With "b" added into riscv/extensions.yaml, a dependency
checking rule is now enforced, which requires that when zba, zbb, and zbs
are all specified, "b" must be added as well. Failing to do this will
cause dtbs_check schema check warnings.

According to uabi.rst, as a single-letter extension, "b" should be added
after "c" in canonical order.

Update dr1v90.dtsi to conform to this rule. Line balancing is performed
to improve readability.
