The Marvell SD8978 (aka NXP IW416) uses identical registers as SD8987,
so reuse the existing mwifiex_reg_sd8987 definition.
Note that mwifiex_reg_sd8977 and mwifiex_reg_sd8997 are likewise
identical, save for the fw_dump_ctrl register: They define it as 0xf0
whereas mwifiex_reg_sd8987 defines it as 0xf9. I've verified that
0xf9 is the correct value on SD8978. NXP's out-of-tree driver uses
0xf9 for all of them, so there's a chance that 0xf0 is not correct
in the mwifiex_reg_sd8977 and mwifiex_reg_sd8997 definitions. I cannot
test that for lack of hardware, hence am leaving it as is.
NXP has only released a firmware which runs Bluetooth over UART.
Perhaps Bluetooth over SDIO is unsupported by this chipset.
Consequently, only an "sdiouart" firmware image is referenced, not an
alternative "sdsd" image.

Support the firmware hotfix version in GET_HW_SPEC responses to avoid an
irritating "Unknown api_id: 5" message on probe.
