Howard Su 8e89496101 Build LUT by fixed point math 
Step 1 to remove float from the code. LUT table can be perfect build by
fixed point math.

lut[i] = (float)i / ((float)255 / ((float)pwm_max - (float)pwm_min)) +
pwm_min;
can be converted to:
lut[i] = (float)i * ((float)pwm_max - (float)pwm_min) / (float)255 +
pwm_min;
can be futher convert to:
lut[i] = i * (pwm_max - pwm_min) / 255 + pwm_min;

The second convertion is validated by a small test code. The first
convertion has slight difference on lut[255] of some combinition of
pwm_max and pwm_min, which I believe second fomula is more accurate.

Howard Su ea65328f7b Use unsigned int when possible 
This reduce the code size significant by two factors:
1. unsigned version can produce less code
2. paramAction can reduce the different versions of templated code

Before;
Sketch uses 27804 bytes (86%) of program storage space. Maximum is 32256 bytes.
Global variables use 1291 bytes (63%) of dynamic memory, leaving 757 bytes for local variables. Maximum is 2048 bytes.

After;
Sketch uses 27418 bytes (85%) of program storage space. Maximum is 32256 bytes.
Global variables use 1291 bytes (63%) of dynamic memory, leaving 757 bytes for local variables. Maximum is 2048 bytes.

Howard Su 3b0064b289 Mark ssb and dsp cap const when non-QCX 
This tells compiler to optimized out all QCX related code. This saves 1216 bytes ROM.
