3b87812f00 Kconfig: Update default hex values to start with 0x 
Kconfig hex values don't need to be in quotes, and should start with
'0x'.  If the default value isn't set this way, Kconfig will add the
0x to the start, and the entry can be added unnecessarily to the
defconfig since it's "different" than what was set by the default.

A check for this has been added to the Kconfig lint tool.

3fd57d8239 kconfig: add missing SPI TPM CS config definition 
To fully define TPM attachment to a SPI interface both bus and CS
(chip select) settings are required. Add the missing CS configuration
option.

BRANCH=none
BUG=chrome-os-partner:50645
TEST=with the rest of the patches applied it is possible to compile in
     and run TPM2 SPI driver.

26588707c5 kconfig: allow various tpm type and interface permutations 
Until now it was assumed that all TPM devices were of the same type
(TCG 1.2 spec compliant) and x86 based boards had LPC connected TPMs
and all other boards had I2C connected TPMs.

With the advent of TPM2 specification there is a need to be able to
configure different combinations of TPM types (TPM or TPM2) and
interfaces (LPC, I2C and SPI).

This patch allows to do it. Picking Chrome OS still assumes that the
board has a TPM device, but adding MAINBOARD_HAS_TPM2 to the board's
Kconfig will trigger including of TPM2 instead.

MAINBOARD_HAS_LPC_TPM forces the interface to be set to LPC, adding
SPI_TPM to the board config switches interface choice to SPI, and if
neither of the two is defined, the interface is assumed to be I2C.

BRANCH=none
BUG=chrome-os-partner:50645
TEST=verified that none of the generated board configurations change
     as a result of this patch. With the rest of the stack in place it
     is possible to configure different combinations of TPM types and
     interfaces for ARM and x86 boards.
