Command timing is the absolute value of the most negative `pi_coding`
value across all ranks, or zero if there are no negative values. Use the
MAX() macro to ease proving that `cmd_delay` can never be negative, and
then drop the always-false underflow check.
The variable type for `cmd_delay` still needs to be signed because of
the comparisons with `pi_coding`, which is a signed value. Using an
unsigned type would result in undefined and also undesired behavior.

Clock is a differential signal and propagates faster than command and
control, therefore its timing needs to be offset with `pi_code_offset`.
It is also a periodic signal, so it can safely wrap around.
To avoid potential undefined behavior, make `clk_delay` signed. It makes
no difference with valid values, because the initial value can be proven
to never be negative and `pi_code_offset` is always positive. With this
change, it is possible to add an underflow check, for additional sanity.

To allow adjusting the phase shift of the various I/O signals, the
memory controller contains several PIs (Phase Interpolators). These
devices subdivide a QCLK (quarter of a clock cycle) in 64 `ticks`,
and the desired phase shift is specified in a register. For shifts
larger than one QCLK, there are `logic delay` registers, which allow
shifting a whole number of QCLKs in addition to the PI phase shift.
The number of PI ticks in a QCLK is often used in raminit calculations.
Define the `QCLK_PI` macro and use it in place of magic numbers. In
addition, add macros for other commonly-used values that use `QCLK_PI`
to avoid unnecessarily repeating `2 * QCLK_PI`, such as `CCC_MAX_PI`.
