Subject: [PATCH v1] hwrng: Kconfig - Do not enable by default CN10K driver

From: Francesco Dolcini <francesco.dolcini@...adex.com>

Do not enable by default the CN10K HW random generator driver.

CN10K Random Number Generator is available only on some specific
Marvell SoCs, however the driver is in practice enabled by default on
all arm64 configs.

as an alternative I could propose

default HW_RANDOM if ARCH_THUNDER=y
