 void hard_reset(void)
 void soft_reset(void)

 According to HT1000 programmers guide 1.3, section "cf9 reset" writing a
 0x6 to 0x0cf9 is hard reset, writing 0x4 is soft reset.
 Current implementation for hard_reset accesses "reserved" bits.
 Current implementation for soft_reset implements hard reset.
 However writing 0x4 as a soft reset does not work in my case.

 Please review/verify.
