When command timeout happens due to a bug in firmware/hardware,
the timeout handler just prints some debug information. User is
unable to reload the driver in this case.
Inspired by 9a821f5 "libertas: add sd8686 reset_card support",
this patch adds card reset support for SDIO interface when
command timeout happens. If the SDIO host contoller supports
MMC_POWER_OFF|UP|ON operations, the chip will be reset and the
firmware will be re-downloaded.

Semicolons are not necessary after macros that end in while (0).
Remove them.
Simplify the macros with tests of
do { if (foo>size) memset1; else memset2;} while (0);
to a single line memset(,,min_t(size_t, foo, size))

For SD8787 A0/A1 chipsets we use the default firmware image
file 'mrvl/sd8787_uapsta.bin'. So the chip rev id variable
is removed.
The global variable fw_name is moved to adapter structure
so that we can support a different interface, such as PCIe,
in future.

While decoding received event packet from firmware, 4 bytes
of interface header are already removed unconditionally.
So for handling event only 4 more bytes needs to be pulled.
This is achieved by changing event header length to 4.
Almost all the events, except BA stream related and AMSDU
aggregation control events, do not have the payload in their
event skb. Such events handling depends only on the event ID.
This event ID is the first four bytes of the event skb, which
is copied to a separate variable before pulling the skb header.
Hence event handling worked only for those events that didn't
have payload in event skb.
This patch fixes the broken event path of the events with
payload in their event skb without harming existing working
event path for the events without payload.

This driver adds WiFi support for Marvell 802.11n based chipsets
with SDIO interface. Currently only SD8787 is supported. More
chipsets will be supported later.
