iwlwifi: Deinline iwl_{read,write}(8,32}
With CONFIG_IWLWIFI_DEVICE_TRACING=y, these functions are rather large,
too big for inlining.
With this .config: http://busybox.net/~vda/kernel_config,
after uninlining these functions have sizes and callsite counts
as follows:
iwl_read32 475 bytes, 51 callsites
iwl_write32 477 bytes, 90 callsites
iwl_write8 493 bytes, 3 callsites
Reduction in size is about 74,000 bytes:
text data bss dec hex filename
