make this driver support it. Also fix some typos while I'm at it.

Add optional blockread function to interface driver. If available
the chip driver uses it for data register access. For 12 bit device
it reads 6 bytes to get 3*16bit data. For 8 bit device it reads out
5 bytes since every second byte is dummy.
This optimizes bus usage and reduces number of operations and
interrupts needed for one data update.

The axis-mapping of lis3dev device on many (rather most) HP machines
doesn't follow the standard.  When each new model appears, users need to
adjust again.  Testing this requires the rebuild of kernel, thus it's not
trivial for end-users.

This patch adds a module parameter "axes" to allow a custom axis-mapping
without patching and recompiling the kernel driver.  User can pass the
parameter such as axes=3,2,1.  Also it can be changed via sysfs.
