During chip probing, if error does not come from secure boot (for
exemple when firmware has been found), others errors probably appears.
It is not necessary to say to user that the error does not come from
secure boot. So, drop the message saying "no error reported by secure
boot".
BTW, we take the opportunity to simplify print_boot_status().

Fix sparse warnings:
drivers/staging/wfx/fwio.c:83:5: warning: symbol 'sram_write_dma_safe' was not declared. Should it be static?
drivers/staging/wfx/fwio.c:229:5: warning: symbol 'load_firmware_secure' was not declared. Should it be static?

A firmware is necessary to run the chip. wfx_init_device() is in charge
of loading firmware on chip and doing low level initialization.
Firmwares for WF200 are available here:
https://github.com/SiliconLabs/wfx-firmware/
Note that firmware are encrypted. Driver checks that key used to encrypt
firmware match with key burned into chip.
Currently, "C0" key is used for production chips.
