libubb/physmem.c (physmem_xlat): make "v" "const"
Since we may use the buffer as well for reading only, there is no point in
pretending physmem_xlat itself would try to write to it.

libubb/mmcclk.c (mmcclk_first): base clock calculation on state of CPCCR.PCS
Also rename BEN_SYS_CLK_HZ to BEN_PLL_CLK_HZ, since the system clock
depends on CPCCR.PCS (while we assume BEN_PLL_CLK_HZ to be constant.)
