Subject: [PATCH] staging: rtl8723bs: Replace magic numbers in rtl8723b_InitBeaconParameters

From: Ashirvad Mohanty <ashirvadm04@...il.com>

Replace magic numbers 0x6404 and 0x660F in rtl8723b_InitBeaconParameters
with macros TBTT_PROHIBIT_TIME_8723B and BCN_AIFS_CFG_8723B, respectively,
defined in rtl8723b_hal.h. This addresses the TODO to remove magic numbers,
improving code readability and maintainability per Linux kernel coding style.
