Agilex retrieves its clock manager address via probing its own clock
driver model during the SPL initialization.
Therefore, excluding Agilex from calling its clock driver in misc
driver to retrieve the clock manager address.
Once all SoC64 devices has been successfully transition to clock
driver model method, this implementation will be cleaned up.

The DDR data rate must be set correctly in the DDRIOCTRL
register according to the Actual Clock Frequency (ACF) value.
By enabling the reading of ACF value from bit 18 of the boot
scratch register during initialization, the DDR data rate is
able to be configured accurately.

Setting up firewall regions based on SDRAM memory banks configuration
(up to CONFIG_NR_DRAM_BANKS banks) instead of using whole address space.
First 1 MiB (0 to 0xfffff) of SDRAM is configured as secure region,
other address spaces are non-secure regions. The ARM Trusted Firmware (ATF)
image is located in this first 1 MiB memory region. So, this can prevent
software executing at non-secure state EL0-EL2 and non-secure masters
access to secure region.
Add common function for firewall setup and reuse for all SoC64 devices.

Asynchronous aborts were previously masked at SPL

To ensure early detection of system errors
such as ECC faults or bus errors, asynchronous aborts
should be explicitly unmasked by clearing the A-bit in

Update the ARMv8 generic timer frequency register (cntfrq_el0)
with the actual hardware timer frequency (COUNTER_FREQUENCY_REAL).
The generic timer frequency was set to 0x200000000 during boot clk
which needs to be set to 0x400000000 when transition from boot clk
to PLL clk.
This will ensure that subsequent timer operations are based on the
correct frequency, ensuring accurate timekeeping.

to receive the return value from rcar_clk_get_table_val which returns an
int and then attempts to test for being less than 0, which can never be
true. Instead declare value as an int so the code can behave as
expected. Also remove initial values from 'value' and 'div' as they are
