iriver_flash: revise cfi_read_id and cfi_get_flash_info

First neither of these functions can fail on supported targets
so they have become void functions. Their return values were
not being used anyway.

Second support for other flash chips not even used on the
supported targets has been removed. It appears they were
only ever used on the discontinued Arch devices.

Third cfi_read_id was restructured to remove obsolete code
for error checking that is not necessary at all. The datasheets
appear to indicate that the commands used cannot fail.

Fourth cfi_get_flash_info was restructured to use a new approach
to initializing the flash_info struct. It no longer initializes
the structure twice.

Fifth the relevant code has been updated to use the full 16 bits
that are exposed by the flash rom ID interface.
