[PATCH 7/8] platform/x86: x86-android-tablets: use 4-argument i2c_smbus_read_block_data()

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

Pass the expected response length and destination buffer directly to
i2c_smbus_read_block_data() in atla10_ec_cmd() instead of copying
through an intermediate buffer.
