changes regarding x, y, and z values in hmc5883l.c

[Suraj151]

in current code of hmc5883l.c it uses
x = (int16_t) ((data[0] << 8) | data[1]);
y = (int16_t) ((data[2] << 8) | data[3]);
z = (int16_t) ((data[4] << 8) | data[5]);

but as per hmc5883l datasheet

0th and 1st bytes are of x axis
2nd and 3rd bytes are of z axis
4th and 5th bytes are of y axis

i.e. it should be

x = (int16_t) ((data[0] << 8) | data[1]);
z = (int16_t) ((data[2] << 8) | data[3]);
y = (int16_t) ((data[4] << 8) | data[5]);

Nope, you created it against master - and I didn't notice 😞. Hence, I had to revert the changes. Please create a new PR.
