[PATCH] media: tegra-vde: Add HAS_IOMEM dependency to match SRAM select

  K002: config VIDEO_TEGRA_VDE selects visible symbol SRAM which has
        dependencies

VIDEO_TEGRA_VDE selects SRAM, which is defined in drivers/misc/Kconfig as:

  config SRAM
      bool "Generic on-chip SRAM driver"
      depends on HAS_IOMEM

The NVIDIA Tegra video decoder driver was originally introduced in
commit cd6c56feb591 ("media: staging: media: Introduce NVIDIA Tegra video decoder
driver")
as a staging driver with `depends on
ARCH_TEGRA || COMPILE_TEST` and
`select SRAM`. Since all Tegra SoCs have HAS_IOMEM, the SRAM dependency was
implicitly satisfied for real hardware configurations.

The driver was later de-staged in commit 8bd4aaf438e3 ("media: staging:
tegra-vde: De-stage driver") and relocated to
drivers/media/platform/nvidia/tegra-vde/ in commit 9b18ef7c9ff4 ("media:
platform: rename tegra/vde/ to nvidia/tegra-vde/"). Throughout these moves,
the `select SRAM` remained without a corresponding HAS_IOMEM dependency.

Under COMPILE_TEST on a hypothetical architecture without HAS_IOMEM (such
as UML in some configurations), the select would force SRAM on without its
HAS_IOMEM dependency being met. Add an explicit `depends on HAS_IOMEM` to
make the dependency chain complete and prevent this misconfiguration under
COMPILE_TEST.
