Fix almost all warnings thrown by dt-check-style after krzk's updates
to the tool [1] when run under the strict mode. There are still a few
warnings remaining which are documented in the relevant commit message.
By doing this the files become easier to read and maintain.
After this patch series only the following warnings are thrown:
arch/riscv/boot/dts/thead/th1520.dtsi:221: [child-name-order] child node 'oscillator' out of name order
arch/riscv/boot/dts/thead/th1520.dtsi:227: [child-name-order] child node '32k-oscillator' out of name order
arch/riscv/boot/dts/thead/th1520.dtsi:248: [property-name] property name "snps,wr_osr_lmt" is using discouraged style
arch/riscv/boot/dts/thead/th1520.dtsi:249: [property-name] property name "snps,rd_osr_lmt" is using discouraged style
arch/riscv/boot/dts/thead/th1520.dtsi:253: [child-name-order] child node 'aon' out of name order
These are left for future work as they create a very large diff.

These were observed when running the tool in strict mode.
