msm: camera: Fix CCI sequential write

This is a fix for 2b490d2c.
The previous change is to allow writing a register address 0x00.
To delete a condition of "if the address is 0", it removed the
multiple data writing part for sequential address. The change
introduces the issue from sequential addreess/data writing.
(Instead of making a packet :
<address_0x20><data_0xA><data_0xB><data_0xC>,
It makes seperate packets with a wrong address. The addresses
of all packets from the second are 0x0 that is not valid. :
<address_0x20><data_0xA>, <address_0x0><data_0xB>, ...)

For proper change, revert the sequential address/data writing
part. But to write the packet which address is actually 0x0,
add the seperate command of "MSM_CCI_I2C_WRITE_SEQ" and
use this condition to differentiate
between normal packet writing and sequential address writing.
