qsd8k: replace scorpion bionic optimizations with linaro

After running proper bench marks with stringbench we see significant
  gains from linaro bionic optimizations

Before (without linaro)
500000000 * strlen(15*a):     43.336822 seconds
1000000   * strlen(15000*a):  33.773773 seconds
10000000  * memchr not finding anything in 15000 chars: 792.615570 seconds
10000000  * strchr not finding anything in 15000 chars: 904.998291 seconds
10000000  * memchr finding match at 5000: 214.158386 seconds
10000000  * strchr finding match at 5000: 302.213776 seconds
After (with linaro)
500000000 * strlen(15*a):     37.743409 seconds
1000000   * strlen(15000*a):  17.071136 seconds
10000000  * memchr not finding anything in 15000 chars: 207.993500 seconds
10000000  * strchr not finding anything in 15000 chars: 453.010101 seconds
10000000  * memchr finding match at 5000:  69.951111 seconds
10000000  * strchr finding match at 5000: 151.385285 seconds

mem{cpy,set} are about the same so go ahead and replace the scropion
  optimizations with linaro (scorpion optimizations were really only
  tested by caf for msm8660 so this is probably for the best)

Scorpion optimizations
10000000  * memset 15000*'a':      168.453034 seconds
10000000  * memcpy of 15000 bytes: 178.014984 seconds
900000000 * memcpy of 15    bytes:  43.154480 seconds
Linaro optimizations
10000000  * memset 15000*'a':      170.355347 seconds
10000000  * memcpy of 15000 bytes: 177.125245 seconds
900000000 * memcpy of 15    bytes:  43.751404 seconds
