For RTL8723BS devices the current config file name is a composite of
both the config name (rtl8723bs) and a postfix of the device-id.

Given the majority of RTL8723BS devices use a device-id of OBDA8723
this simplifies the config file name to use "rtl8723bs_config.bin"
as a default of for these devices.

NACK, the device id is in there for a reason, once someone writes
support for it we will also need a rtl8723bs_config file on ARM
boards, which will definitely be board specific. I don't want us
to pretend there is one config to rule them all.

Specifically I plan to submit both the firmware and
rtl8723bs_config-OBDA8723.bin to linux-firmware soon, if the kernel
instead looks for just rtl8723bs_config.bin then I need to give
it that name in linux-firmware and then when we get ARM support
and the kernel complains about e.g. rtl8723bs_config-NextThingCo-CHIP.bin
not being there people may be tempted to think they can just link
to the "generic" one from linux-firmware which then turns out
to not be generic at all.
