This patch represents TSC freqeuency in KHz using a 32-bit unsigned integer.
The conversion macros between ticks and us/ms are changed to inline functions to
enforce the types of the input parameters. Note that us_to_ticks accepts only
uint32_t (~4K us at most) and never overflows.
Results of some unit tests on the conversion functions:
calibrate_tsc, tsc_khz=1881600
64us -> ticks: 120422
64us -> ticks -> us: 63
511us -> ticks: 961497

This patch resolved systemd be blocking for 20 seconds due to waiting the
"READY=1" from cbc_attach. And cbc_attach will retry 60 sec at the worst case
which can be reproduced on non-IOC boards.
This is one temporary solution. The final solution need modify SBL to export IOC
ACPI device through ACPI table, and also Linux IOC CBC driver need trigger
uevent which should be the trigger of launching cbc_attach service.
This patch changes the service type to simple instead of notify due to systemd is
needn't wait cbc related services. And change Restart to no due to cbc_attach
already has retry mechanism.
These changes are also reasonable for the board integrated IOC component.
So they should be keep even the long term final solution implemented.

PIC pin IDs should be logically unsigned, while we currently use ''int'' to
represent them.
Following the convention we use unsigned IDs, this patch converts the
representation of pins to uint8_t. A special value VPIC_INVALID_PIN is
introduced to represent the case when a valid target pin cannot be
found (previously -1 is used for this case). The branch conditions are updated
accordingly, following the convention below.
(for ''pin''s representing a per-PIC pin)
if (pin != -1) -> if (pin < NR_VPIC_PINS_PER_CHIP)
if (pin == -1) -> if (pin >= NR_VPIC_PINS_PER_CHIP)
if (pin >= 0 && pin < 8) -> if (pin < NR_VPIC_PINS_PER_CHIP)
if (pin >= 0 && pin <= 7) -> if (pin < NR_VPIC_PINS_PER_CHIP)
if (pin >= 0) -> if (pin < NR_VPIC_PINS_PER_CHIP)
(for ''pin''s representing a pin in the vPIC with 2 cascading PICs)
if (pin >= 0 && pin <= 15) -> if (pin < NR_VPIC_PINS_TOTAL)
if (pin > 15) -> if (pin >= NR_VPIC_PINS_TOTAL)
Related local variables are also changed accordingly.
v1 -> v2:
* Rename the number of pins per PIC to NR_VPIC_PINS_PER_CHIP, and the number
of pins of 2 cascading PICs to NR_VPIC_PINS_TOTAL.
* Using "%hhu" instead of "%d" in format string when a pin is expected.
