arm64/mpam: Fix wrong seconds to jiffies conversion

--------------------------------

According to the comment:

  jiff = (sec) * (NSEC_PER_SEC / NSEC_PER_JIFFIE);
  jiff = ((sec) * ((NSEC_PER_SEC * SCALE)/ NSEC_PER_JIFFIE)) / SCALE;
  Then we make SCALE a power of two so:
  jiff = ((sec) * ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE)) >> SCALE;
  Now we define:
  #define SEC_CONV = ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE))
  jiff = (sec * SEC_CONV) >> SCALE;

Fix the incorrect seconds to jiffies conversion.
