PSoC 62/63: set correct mbed_ram_start and mbed_ram_size

In case when target.mbed_ram_start and target.mbed_ram_size are not set
neither in targets.json nor in mbed_app.json, the IRAM1 region values
defined in tools/arm_pack_manager/index.json are passed by Mbed CLI as
the linker script preprocessing flags. As a result, wrong addresses of
MBED_RAM_START and MBED_RAM_SIZE are defined in the linker script since
CMSIS DFP pack has no information about RAM split between CM0+ and CM4 applications.

Set the values explicitly in targets.json to ensure the correct RAM layout.

The MBED_ROM_START and MBED_ROM_SIZE provided by CMSIS DFP are already
correct since the linker scripts places CM4 vector table at MBED_APP_START,
taking into account the flash application area of the CM0+ prebuilt application.
