tcl/target: Add Renesas R-Car Gen3 targets

Add configuration for the Renesas R-Car Generation 3 targets.
These are SoCs with Cortex A57s, A53s, and R7s. All cores
are supported.

+# Renesas R-Car Generation 3 SOCs
+# - There are a combination of Cortex-A57s, Cortex-A53s, and Cortex-R7 for each Gen3 SOC
+# - Each SOC can boot through any of the, up to 3, core types that it has
+#   e.g. H3 can boot through Cortex-A57, Cortex-A53, or Cortex-R7
+
+# Supported Gen3 SOCs and their cores:
+#  H3: Cortex-A57 x 4, Cortex-A53 x 4, Cortex-R7 x 2 (Lock-Step)
+# M3W: Cortex-A57 x 2, Cortex-A53 x 4, Cortex-R7 x 2 (Lock-Step)
+# M3N: Cortex-A57 x 2,                 Cortex-R7 x 2 (Lock-Step)
+# V3H:                 Cortex-A53 x 4, Cortex-R7 x 2 (Lock-Step)
+# V3M:                 Cortex-A53 x 2, Cortex-R7 x 2 (Lock-Step)
+#  E3:                 Cortex-A53 x 1, Cortex-R7 x 2 (Lock-Step)
+#  D3:                 Cortex-A53 x 1
+
+# Usage:
+# There are 2 configuration options:
+# SOC:       Selects the supported SOC. (Default 'H3')
+# BOOT_CORE: Selects the booting core. 'CA57', 'CA53', or 'CR7'
+#            Defaults to 'CA57' if the SOC has one, else defaults to 'CA53'
