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.

I don't really think these names add any information.  The number is
related to TIME but no one really knows how it works.  Someone posted
a theory about it, but it turned out that was just AI hallucination.
The spec they quoted was real but the sub section was fake.

The 8723B is the name of the driver, but without the "s" for some
reason.  It's just words but with no meaning.  It's a map to nowhere.
It's a waste of time.  I would say that there is also an element where
these names are a bit misleading because the BCN_AIFS_CFG_8723B is
really specific and the name suggests it's more of a generally config
button.

Just leave it as-is.  I would suggest that you could delete the TODO,
but it's good practice to just learn to accept that we can't fix
everything.
