ARM: configs: multi_v5_defconfig: remove deleted platforms

Some ARMv5 platforms got removed from the kernel over time, so we don't
need their symbols in the multi_v5_defconfig anymore:

- ARCH_U300 got removed with commit ce1380c9 ("ARM: remove u300
  platform"), so CONFIG_ARCH_U300 is not around anymore.
- ARCH_U300 was the only platform selecting ARCH_AMBA, which I2C_NOMADIK
  depends on. So we won't need this symbol anymore, and can't select it
  anyway.
- i.MX27 got converted to DT in 879c0e5e ("ARM: imx: Remove i.MX27
  board files"). Remove the now obsolete board file version symbols.

No change in the generated .config or savedefconfig.
