[PATCH v5] staging: rtl8723bs: Improve clarity of MAR usage

[Manjae Cho <manjae.cho@samsung.com>]

This patch improves the readability of the code related to the Multicast
Address Register (REG_MAR) in the rtl8723bs driver. It adds comments to
clarify the purpose and offset of the register, making the code more
self-documenting without introducing new macros.
