The FWSEND parameter controls the size of the firmware chunks sent
down the I2C bus to the chip. Previously this had been set to 1024
but unfortunately some I2C implementations can't transfer data in such
big gulps. Specifically, the pvrusb2 driver has a hard limit of
around 60 bytes, due to the encapsulation there of I2C traffic into
USB messages. So we have to significantly reduce this parameter.

Remove the assumption that acpi_bus_register_driver() returns the number of
devices claimed. Returning the count is unreliable because devices may be
hot-plugged in the future (admittedly not applicable for this driver).
Since the hardware for this driver is not hot-pluggable, determine whether the
hardware is present by noticing calls to the .add() method. It would be
better to probe the ACPI namespace for the ASUS HIDs, and load the driver only
when we find one, but ACPI doesn't support that yet.
I don't have an ASUS laptop to test on, but on my HP dl360, it does report the
appropriate error when attempting to load the module:

Fix resource_type handling for QWORD, DWORD, and WORD Address Space
Descriptors. Previously we ignored the resource_type, so I/O ports and bus
number ranges were incorrectly parsed as memory ranges.
Sample PCI root bridge resources from HP rx2600 before this patch:
# cat /sys/bus/pnp/devices/00:02/resources
state = active
mem 0x0-0x1f
mem 0x0-0x3af
mem 0x3e0-0x1fff
mem 0x80000000-0x8fffffff
With this patch:
# cat /sys/bus/pnp/devices/00:02/resources
state = active
io 0x0-0x3af
io 0x3e0-0x1fff
mem 0x80000000-0x8fffffff
mem 0x80004000000-0x80103fffffe
Changes:
0x0-0x1f PCI bus number range was incorrectly reported as memory, now
not reported at all
0x0-0x3af I/O port range was incorrectly reported as memory
0x3e0-0x1fff I/O port range was incorrectly reported as memory
0x80004000000-0x80103fffffe memory range wasn't reported at all because
