Subject: [PATCH v6 04/13] dt-bindings: mtd: brcmnand: Updates for bcmbca SoCs

Update the descriptions to reflect different families of broadband SoC and
use the general name bcmbca for ARM based SoC.

Remove the requirement of interrupts property to reflect the driver
code and only require interrupt-names when interrupts property present.

Also add myself to the list of maintainers.

Changes in v6:
- Add reviewed-by tag

Changes in v5:
- Add reviewed-by tag

Changes in v4:
- Split the yaml changes into three patches. This is the first one

Changes in v3:
- Update brcm,nand-use-wp description
- Revert the description change to BCM63168 SoC-specific NAND controller

Changes in v2:
- Revert the new compatible string nand-bcmbca
- Drop the BCM63168 compatible fix to avoid any potential ABI
incompatibility issue
- Simplify the explanation for brcm,nand-use-wp
- Keep the interrupt name requirement when interrupt number is specified
