Writes the given buffer sequentially to a range of 8-bit I2C registers of the specified device.
The maximum input buffer size is 0x200 for the New3DS i2c-sysmodule, and 0x10 for the Old3DS version.
For example, writing a buffer of consisting of { 0xAA, 0xBB, 0xCC, 0xDD } with starting register 0x5 would do the following:
reg[0x5] = 0xAA
reg[0x6] = 0xBB
reg[0x7] = 0xCC
reg[0x8] = 0xDD
