The printed address ranges in the tree (resource allocator and even
some MTRR code) usually shows the range inclusive (meaning from start
address to the real end address of the range). Though there is still
some code in the MTRR context which prints the ranges with an exclusive
end. This patch aligns the printing of ranges in the MTRR code to be
consistent among the tree so that the shown end addresses are now
inclusive.

Commit 3ba6f8cdf (drivers/intel/fsp2_0: Add native implementation for
FSP Debug Handler) implements a native FSP debug handler.
However, coreboot still can't control when to redirect FSP debug
output to the serial console, i.e., at present, integrating a FSP debug
binary is enough to output FSP serial messages irrespective of whether
user is intended to see FSP debug log.
coreboot needs additional mechanism to control FSP debug binary to
redirect debug messages over serial port. This patch introduces a
config `FSP_ENABLE_SERIAL_DEBUG` to control the FSP debug output, user
to enable this config from site-local config file in case like to override
the default FSP serial redirection behaviour in more controlled way from
coreboot.
There could be scenarios as below:
Scenario 1: coreboot release image integrated with the FSP debug
binaries, is capable of redirecting to the serial console, but coreboot
decides to override the config as below to skip FSP debug output
redirection to the serial port.
`#`FSP Serial console disabled by default (do not remove)
`#`CONFIG_FSP_ENABLE_SERIAL_DEBUG is not set
Scenario 2: For coreboot serial image with FSP debug binaries integrated
but coreboot decides to skip FSP debug output redirection to the serial
port.
`#`FSP Serial console disabled by default (do not remove)
`#`CONFIG_FSP_ENABLE_SERIAL_DEBUG is not set
CONFIG_CONSOLE_SERIAL=y
CONFIG_CONSOLE_SERIAL_115200=y
CONFIG_UART_DEBUG=y
CONFIG_UART_FOR_CONSOLE=0
Scenario 3: The final image could be a coreboot serial image with FSP
serial redirection enabled to output to the serial port.
CONFIG_FSP_ENABLE_SERIAL_DEBUG=y
CONFIG_CONSOLE_SERIAL=y
CONFIG_CONSOLE_SERIAL_115200=y
CONFIG_UART_DEBUG=y
CONFIG_UART_FOR_CONSOLE=0
BUG=b:227151510
TEST=Able to build and boot google/redrix with all scenarios between #1--#3
and able to meet the expectation as mentioned above.

Commit 7a87433091 (mb/google,samsung: Drop
init_bootmode_straps()) got rid of the `mainboard_early_init()` function
call and weak definition in Sandy Bridge code. However, this function is
still used by several Sandy Bridge mainboards, so bring back the dropped
call and weak definition.
The aforementioned commit did not cause any build-time errors because it
did not remove the `mainboard_early_init()` function declaration.
