drivers/rtc/rtc-ds1307.c: long block operations bugfix

The rtc-ds1307 driver does not properly handle block operations bigger
than 32 bytes in either of the two modes supported (SMbus native, or
emulated if not supported by the SMbus platform driver).

It also does not properly handle userland-supplied input (block operation
length) through sysfs and may suffer a type of buffer overrun.

The driver has been modified with proper input validation, buffer sizes,
and now splits block transfers bigger than 32 bytes into separate
transfers.

Explanation : Buffer size allocated is I2C_SMBUS_BLOCK_MAX which equals to
32 as per the SMbus spec.  Reads and write may be up to 56 bytes (to the
NVRAM).  This patch allocated a 255 byte buffer, the maximum allowable
(address is an u8).  It's not only a buffer problem, SMbus only supports
up to 32 bytes transfer at once, so it's needed to split bigger transfers.

Patch successfully tested on 3.2.27; cleanly applies on 3.7-rc4.

CONFIG_PM doesn't actually enable any of the PM callbacks, it only allows
to enable CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME.  This means if CONFIG_PM
is used to protect system sleep callbacks then it may end up unreferenced
if only runtime PM is enabled.  Hence protecting sleep callbacks with

Using gpio_request_array()/gpio_free_array() can make the code simpler
because it can set the direction and initial value in one shot and the for
loop is unnecessary.

Also, struct v3020_gpio is removed, because the struct v3020_gpio is
replaced with struct gpio.
