soc/intel: Improve CONFIG_ACPI_SOC_INTEL_SLP_S0_FREQ_HZ use

Commit bd9c562a9e0c6af65f5e798a17ba9a55892ef082 ("acpi: Configure
slp-s0 residency counter frequency in LPIT table") led to jenkins
reporting the following error:

    !!!!! Error: defined(CONFIG_ACPI_SOC_INTEL_SLP_S0_FREQ_HZ)
          used at src/include/acpi/acpi.h:457.  Symbols of type 'hex'
	  are always defined.

Since hex Kconfig are always defined there is no need to test it being
defined but also no need to handle zero or non-zero values.

In addition:

1. This config was defined in Meteor Lake specific Kconfig file while
   it should actually be define closer to where it is being used (here
   soc/intel/common/block/acpi/Kconfig) and only set by the SoC Kconfig.

2. Once moved and under control of `SOC_INTEL_COMMON_BLOCK_ACPI_LPIT'
   gating (lpit.c), the Kconfig name needed to be adjusted to better fit
   its use.

3. Make Meteor Lake Kconfig sets the config but does not define it
   anymore.

TEST=LPIT ACPI table Counter Frequency field is set to 0x2005 on rex
