Several clock controller drivers define a list of clk_hw devices, and then
register those devices in probe() before using common code to process the
rest of initialization. Extend the common code to accept a list of clk_hw
devices to process, thus eliminating many duplicate implementations.

- It has 3 general purpose clock controller which supplies
the clock in GPIO pins.
- It has Crypto Engine which has AXI, AHB and Core clocks.
Other non APSS processors can also use Crypto Engine so
these clocks are marked as VOTED clocks.

IPQ8074 has 6 ethernet ports which supports all ethernet speeds
from 10Mpbs to 10 Gpbs and each speed requires different clock
rates. Each port has separate TX and RX clocks. These clocks
use separate external UNIPHY PLL’s which will be registered with
separate NSS driver. The clock frequency is 125 Mhz for UNIPHY0
and 312.5 Mhz for UNIPHY1 and UNIPHY2.

IPQ8074 has NSS (Network Switching System) which has 2 UBI cores
and hardware crypto engine. Some clocks are separate for each UBI
core and remaining NSS clocks are common. The BIAS_PLL (300 Mhz)
and BIAS_PLL_NSS_NOC (416.5 Mhz) are external fixed clocks and
will be registered from dtsi or NSS driver.

- It has 2 instances of PCIE which uses AXI, AHB, AUX, SYS NOC
AXI and PIPE clocks.
- It has 2 instances of USB 3.0 which uses AUX, SLEEP, PIPE,
SYS NOC, mock UTMI and master clocks.
- It has 2 instances of SDCC which uses APSS and AHB clock.
SDCC1 requires ICE core clock also.
- All the PIPE clocks are external clocks which will be
registered in clock framework by PHY drivers. The enabling
and disabling of PIPE RCG clocks are dependent upon PHY
initialization sequence so BRANCH_HALT_DELAY flag is required for
these clocks.

- GPLL2, GPLL4 and GPLL6 are general PLL clocks and parent
for all core peripherals.
- UBI PLL is mainly used by NSS (Network Switching System).
IPQ8074 has 2 instances of NSS UBI cores and UBI PLL will
be used to control the core frequency.
- NSS Crypto PLL is mainly used by NSS Crypto Engine which
supports the multiple cryptographic algorithm used in
Ethernet.
- IPQ8074 frequency plan does not require change in PLL post
dividers so marked the same as read-only.

Alpha PLL is a generic name used for QCOM PLLs which uses L and
Alpha values for configuring the integer and fractional part.
QCOM SoCs use different types of Alpha PLLs for which basic
software configuration part is common with following differences.
1. All these PLLs have the same basic registers like
PLL_MODE, L_VAL, ALPHA_VAL but some of the register offsets are
different between PLLs types.
2. The dynamic programming sequence is different in some
of the Alpha PLLs
3. Some of the PLLs don’t have 64 bit config control, 64 bit
user control, VCO configuration, etc.
