Subject: [PATCH] clk: at91: fix count of periph clocks passed to pmc_data_allocate
Date:   Wed,  9 Jun 2021 10:01:44 +0200

When allocating clk_hw structure, only the periph32 clocks are considered.
Since sama5d2_periphck are also added to the phws there is currently an
out of bound write. Fix this by adding the count of periphck to periph32ck.
